'''Buenos Aires''',{{efn|{{IPA|es|ˈbwenos ˈajɾes}}}} officially the '''Buenos Aires Province''',{{efn|''Provincia de Buenos Aires'' {{IPA|es|pɾoˈβinsja ðe ˈβwenos ˈajɾes}}}} is the largest and most populous [[Provinces of Argentina|Argentine province]]. It takes its name from the city of [[Buenos Aires]], the capital of the country, which used to be part of the province and the province's capital until it was [[Federalization of Buenos Aires|federalized]] in 1880. Since then, in spite of bearing the same name, the province does not include Buenos Aires city, though it does include all other parts of the [[Greater Buenos Aires]] metropolitan area. The capital of the province is the city of [[La Plata]], founded in 1882.

It is bordered by the provinces of [[Entre Ríos Province|Entre Ríos]] to the northeast, [[Santa Fe Province|Santa Fe]] to the north, [[Córdoba Province, Argentina|Córdoba]] to the northwest, [[La Pampa Province|La Pampa]] to the west, [[Río Negro Province|Río Negro]] to the south and west and the Autonomous City of Buenos Aires to the northeast. [[Uruguay]] is just across the [[Rio de la Plata]] to the northeast, and both are on the coast of the [[Atlantic Ocean]] to the east. Almost the entire province is part of the [[Pampas]] geographical region, with the extreme south often considered part of the [[Patagonia]] region.

The province has a population of about 17.5 million people, which is 38% of Argentina's total population. The province covers an area of {{convert|307571|km2|abbr=on}}, which is about 11% of Argentina's total area and makes it the country's largest province.

==History==
[[File:Juan Manuel de Rosas.jpg|thumb|left|200px|Governor [[Juan Manuel de Rosas]] (1841 oil portrait by [[Cayetano Descalzi]]) ruled until 1852 with an [[Totalitarianism|iron fist]] and kept the fragile [[Argentine Confederation|Confederation]] under the tutelage of Buenos Aires Province.]]
The inhabitants of the province before the 16th-century advent of [[Spanish colonization of the Americas|Spanish colonization]] were [[indigenous people|aboriginal peoples]] such as the [[Charrúa]]s and the [[Querandí]]es. Their culture was lost over the next 350 years. They were subjected to Eurasian plagues from which few survived. The survivors joined other [[tribe]]s or have been mostly absorbed by Argentina's [[European ethnic groups|European]] immigration.

[[Pedro de Mendoza]] founded ''[[Buenos Aires|Santa María del Buen Ayre]]'' in 1536. Even though the first contact with the aboriginals was peaceful, it soon became hostile. The city was evacuated in 1541. [[Juan de Garay]] re-founded the settlement in 1580 as ''Santísima Trinidad y Puerto Santa María de Los Buenos Aires''.

Amidst ongoing conflict with the aboriginals, the cattle farms extended from [[Buenos Aires]], whose port was always the center of the economy of the territory. Following the creation of the [[Viceroyalty of the Río de la Plata]] at the end of the 18th century, the export of meat, leather and their derivatives through the port of Buenos Aires was the basis of the economic development of the region.

[[Jesuit]]s unsuccessfully tried to peacefully assimilate the aboriginals into the European culture brought by the [[Spanish people|Spanish]] conquistadores. A certain balance was found at the end of the 18th century when the [[Salado River (Buenos Aires)|Salado River]] became the limit between both civilizations, despite frequent ''[[malón|malones]]'' (aboriginal attacks on border settlements). The end to this situation came in 1879 with the [[Conquest of the Desert]] (''Conquista del Desierto'') in which the aboriginals were almost completely exterminated.
[[File:1 decimo, Argentina, province of Buenos Aires, 1822.jpg|thumb|left|200px|1 [[Decimo (coins)|decimo]] coin minted for the province in 1822. The reverse features the provincial coat of arms.]]

After the independence from [[Spain]] in 1816, the city and province of Buenos Aires became the focus of an intermittent [[Argentine Civil War]] with other provinces. A [[Pacto Federal|Federal Pact]] secured by Governor [[Juan Manuel de Rosas]] in 1831 led to the establishment of the [[Argentine Confederation]] and to his gaining the [[sum of public power]], which provided a tenuous unity. Ongoing disputes regarding the influence of Buenos Aires, between [[Federalist Party (Argentina)|Federalists]] and [[Unitarian Party|Unitarians]], and over the [[Port of Buenos Aires]] (the prime source of public revenue at the time) fueled periodic hostilities. The province was declared independent on 11 September 1852, as the [[State of Buenos Aires]]. Concessions gained in 1859 [[Pact of San José de Flores]] and a victory at the [[Battle of Pavón]] led to its reincorporation into the Argentine Republic on 17 December 1861. Intermittent conflicts with the nation did not truly cease until 1880, when the city of Buenos Aires was formally [[Federalization of Buenos Aires|federalized]] and, thus, administratively separated from the province.

[[File:Fundación La Plata.jpg|thumb|right|Period illustration of the 1882 placement of La Plata's [[foundation stone]].]]
[[La Plata]] was founded in 1882 by Governor [[Dardo Rocha]] for the purpose of becoming the provincial capital. The equivalent of a billion (1880s) dollars of British investment and pro-development, education and immigration [[Generation of '80|policies]] pursued at the national level subsequently spurred dramatic economic growth. Driven by [[Immigration in Argentina|European immigration]] and improved health, the province's population, like Argentina's, nearly doubled to one million by 1895 and doubled again by 1914.<ref name="indec">{{cite web |title=Población según los censos nacionales de 1895 a 2001 por provincia ordenadas por la cantidad de población en 2001 |url=http://www.indec.mecon.gov.ar/nuevaweb/cuadros/2/pobl_1895-01.xls |format=ms xls |publisher=Instituto Nacional de Estadística y Censos |language=es |access-date=14 August 2012 |url-status=dead |archive-url=https://web.archive.org/web/20120213191403/http://www.indec.mecon.gov.ar/nuevaweb/cuadros/2/pobl_1895-01.xls |archive-date=13 February 2012}}</ref> [[Rail transport in Argentina|Rail lines]] connected nearly every town and hamlet in the province by 1914; many developed around the new railway stations.

This era of accelerated development was cut short by the [[Wall Street crash of 1929]], which caused a sharp drop in commodity prices (99% of Argentine exports were agricultural) and led to a halt in the flow of investment funds between nations. The new [[Concordancia (Argentina)|Concordance]] and [[Juan Perón|Perón]] governments funded ambitious lending and public works programs, visible in Buenos Aires Province through the panoply of levees, power plants, water works, paved roads, municipal buildings, and (particularly during Perón's 1946-55 tenure) schools, clinics and massive regional hospitals.

The province's population, after 1930, began to grow disproportionately quickly in the suburban areas of Buenos Aires. These suburbs had grown to include 4 million out of the province's total 7 million people in 1960.<ref name="indec" /> Much of the area these new suburbs were developed on (particularly the poorer ones) consisted of wetlands and were prone to flooding. To address this, Governor [[Oscar Alende]] initiated the province's most important flood-control project to date, the Roggero Reservoir. Completed a decade later, in 1971, the reservoir and associated electric and water-treatment facilities encouraged still more, and more orderly, development of the [[Greater Buenos Aires]] region, which today includes around 10 million people ({{frac|2|3}} of the provincial population). It did not address worsening pollution resulting from the area's industrial growth, which had made itself evident since around 1920. This problem has been at its worst along the [[Reconquista River]] west and north of the city of Buenos Aires; over 4 million people (one in 10 Argentines) today live on the Reconquista's basin.<ref>{{cite web |url=http://www.unsam.edu.ar/home/rr.pdf |title=Title unknown |language=es |url-status=dead |archive-url=https://web.archive.org/web/20080912122242/http://www.unsam.edu.ar/home/rr.pdf |archive-date=12 September 2008}}</ref> Of these, about a million still live with seriously compromised water quality, despite the province's (sometimes counterproductive) efforts to remedy the issue.<ref>

===Contemporary history===
In [[2013 Argentina floods|April 2013]], the northeastern section of Buenos Aires Province, particularly its capital, La Plata, experienced several flash floods that claimed the lives of at least 89 people.<ref>{{cite news |last1=Corsalini |first1=Claudio |title=Diez años de la trágica inundación en La Plata: dudas sobre la cantidad de muertos y una multa de $ 12 mil |url=https://www.perfil.com/noticias/sociedad/diez-anos-de-la-tragica-inundacion-en-la-plata-dudas-sobre-la-cantidad-de-muertos-y-una-multa-de-12-mil.phtml |access-date=20 April 2024 |work=[[Perfil]] |date=1 April 2023 |language=es}}</ref>

[[Alejandro Armendáriz]], of the [[Radical Civic Union]], was elected governor in 1983, when [[Raúl Alfonsín]] became president. Alfonsín lost the [[1987 Argentine legislative election|1987 midterm elections]], leading to the victory of [[Antonio Cafiero]]. From then to 2015, all governors have been Peronists. The high population of the province makes it highly influential in Argentine politics. With both ruling for two terms, the rivalry of the president [[Carlos Menem]] and governor [[Eduardo Duhalde]] dominated the Argentine politics during the nineties. A similar case took place with the president [[Cristina Fernández de Kirchner]] and governor [[Daniel Scioli]]. [[María Eugenia Vidal]], from [[Republican Proposal]], won the 2015 elections, and became the first female governor of the province.<ref>{{cite web |url=http://www.lanacion.com.ar/1839835-vidal-dio-la-gran-sorpresa-y-le-gano-a-anibal-fernandez-en-la-provincia |title=Vidal dio la gran sorpresa y le ganó a Aníbal Fernández en la provincia |trans-title=Vidal gave a great surprise and defeated Aníbal Fernández in the province |language=es |author=Ramiro Sagasti |date=26 October 2015 |publisher=La Nación |access-date=26 October 2015 |archive-date=13 January 2018 |archive-url=https://web.archive.org/web/20180113003753/http://www.lanacion.com.ar/1839835-vidal-dio-la-gran-sorpresa-y-le-gano-a-anibal-fernandez-en-la-provincia |url-status=dead}}</ref>

[[File:Juzgados Federales-La Plata-1.jpg|thumb|Federal courts in La Plata]]

The provincial government is divided into three branches: the executive, headed by a popularly elected [[Governor of the Buenos Aires Province|governor]], who appoints the cabinet; the [[Legislative branch|legislative]] (represented by the [[Legislature of Buenos Aires Province|Legislature]], which is split into the [[Buenos Aires Province Chamber of Deputies|Chamber of Deputies]] and the [[Buenos Aires Province Senate|Senate]]); and the [[Law of Argentina|judiciary]], headed by the Supreme Court.

The Constitution of Buenos Aires Province forms the formal law of the province.

In Argentina, the most important law enforcement organization is the [[Argentine Federal Police]], but the province is policed by its own [[Buenos Aires Provincial Police]].

==Geography==
Buenos Aires Province, at {{convert|307571|km2}}, is slightly bigger than [[Italy]]. The landscape is mainly flat, with two low mountain ranges: ''[[Sierra de la Ventana (mountains)|Sierra de la Ventana]]'' (near [[Bahía Blanca]]) and ''Sierra de Tandil'' ([[Tandil]]). The highest point is ''Cerro Tres Picos'' ({{convert|1239|m|ft|0|abbr=on}} [[Above mean sea level|amsl]]; {{coord|38|8|S|61|58|W}}) and the longest river is ''[[Salado River (Buenos Aires)|Río Salado]]'' ({{convert|700|km|mi|0|abbr=on}} long).

As part of [[Pampa|The Pampas]], the weather of the province is strongly influenced by the ocean, with hot summers and temperate winters. Humidity is high and precipitation is abundant and distributed over the year. The Western and Southwestern regions are drier and are part of the [[Semi-arid Pampas]] ecoregion. The southernmost part of the province is often included in definitions of the [[Patagonia]] region.<ref>{{cite web |title=Visitá la Patagonia Bonaerense |url=https://www.buenosaires.tur.ar/nota/visita-la-patagonia-bonaerense |publisher=Undersecretariat of Tourism of Buenos Aires Province |access-date=2 January 2022 |language=es |archive-date=2 January 2022 |archive-url=https://web.archive.org/web/20220102044909/https://www.buenosaires.tur.ar/nota/visita-la-patagonia-bonaerense |url-status=live }}</ref>

===Climate===
{{see also|Climate of Argentina|Climatic regions of Argentina}}
[[File:Buenos Aires Köppen.svg|thumb|Köppen climate map of Buenos Aires.]]
[[File:Mdp nevada-1991-2.jpg|thumb|Snow on La Perla beach, [[Mar del Plata]] (1991).]]

The climate of the province of Buenos Aires is extremely benign for human activities: it is temperate, with four marked seasons and reliable rainfall on most regions. The province can be divided into four main climatic regions: the southwestern, drier region; the cool Atlantic region; the northern and eastern humid region, and the Delta region, with the warmest, wettest climate.

The northern region has warm, humid summers, with days between {{convert|28|and|32|C|F}} and nights between {{convert|16|and|20|C|F}}, pleasant falls, cool, drier winters with highs between {{convert|13|and|18|C|F}} and nights between {{convert|2|and|5|C|F}}, and windy, variable springs. Heat waves may bring days with temperatures over {{convert|38|C|F}}, but these do not usually last very long, as cold fronts bring thunderstorms and cooler days, with night temperatures often falling down to {{convert|12|C|F}}. Winter cold waves may bring days with highs about {{convert|8|C|F}}, and lows below {{convert|-4|C|F}}, with extremes down to {{convert|-8|C|F}}. Snow is uncommon, but there have been accumulations on several occasions in the past. Precipitation ranges from {{convert|750|to|1100|mm|abbr=on}} per year.

The Delta region is slightly warmer, especially at night, due to the presence of water and the northerly location. Summer nights tend to be stickier, and winters can be damp and foggy, with most nights between {{convert|4|and|8|C|F}}. Frost is still to be expected, but temperatures will almost never fall below {{convert|-4|C|F}}, and snow has fallen only twice in the last century. Precipitation ranges from {{convert|1000|to|1300|mm|abbr=on}} and falls throughout the year. The city of Buenos Aires is surrounded by a climate similar to the northern part of the province, but the city itself resembles more the Delta climate, with less frost.

The southwestern region is the driest region, and it experiences a more marked differences in temperatures. Summers are often hot, between {{convert|30|and|35|C|F}}, but nights are usually comfortable ({{convert|14|to|18|C|F}}). Thunderstorms are less frequent but can be very violent in nature. Frost can make an appearance as early as March, but usually first comes in April. Winters are cool and dry, with days between {{convert|10|and|16|C|F}} and nights between {{convert|-1|and|4|C|F}}. Frost occurs on an almost daily basis, with temperatures below {{convert|-6|C|F}} not uncommon, and down to {{convert|-12|C|F}} recorded in some areas. Snowfall may occur every once in a while, but accumulations are usually small. Total precipitation ranges from {{convert|500|to|750|mm|abbr=on}}, with slightly rainier springs and falls.

The Atlantic region sees very moderate weather: the ocean is cold ({{convert|17|to|20|C|F}} in the summer) and sea breezes often bring chilly weather until midsummer. The hottest months average {{convert|25|to|27|C|F}} with nights between {{convert|12|and|16|C|F}}, providing a perfect relief for the inhabitants of the hotter interior. Fall is often rainy, and winters can be windy and chilly: temperatures average from {{convert|10|to|15|C|F}}, and nights from {{convert|1|to|5|C|F}}. There can be long periods of drizzly weather and constant temperatures of about {{convert|7|C|F}}. Frost is common but temperatures will rarely fall below {{convert|-5|C|F}}, and snowfalls sometimes, but accumulations are only to be expected every few years. Precipitation ranges from {{convert|700|to|950|mm|abbr=on}}. The Sierras de la Ventana (up to {{convert|1200|m}}) experience cooler weather, especially at night.

The geography of the province is crossed by occasional west [[Pampero Winds|Pampero winds]]. The southern ''[[Sudestada]]'' produces storms and temperature drops, most notably the ''Santa Rosa'' storm,<ref>{{cite web |url=http://www.monte.gov.ar/planificacion/informacionutil1/climatolofia/santarosa.htm |title=Title unknown |publisher=monte.gov.ar |url-status=dead |archive-url=https://web.archive.org/web/20051226131555/http://www.monte.gov.ar/planificacion/informacionutil1/climatolofia/santarosa.htm |archive-date=26 December 2005}}</ref> which takes place every year almost exactly on 30 August.

[[File:Argentina Buenos Aires location map.svg|thumb|right|Boundaries of the 135 ''partidos'' of Buenos Aires Province]]
Unlike the other provinces of the country, in the province of Buenos Aires, the territorial divisions are called ''[[Partidos of Buenos Aires|partidos]]'', instead of departments.

These also constitute the municipal division of the province. The provincial Constitution does not recognize the municipal autonomy that was recognized for the whole country in the reform of the [[Constitution of Argentina|National Constitution]] of 1994. Each partido corresponds to a [[municipality]] and is governed by a mayor (''[[Intendant (government official)#Argentina|intendente]]'') elected by popular vote. The process of creating a partido is much more dynamic than in the other provinces, with a total of six more partidos in 2000 than in 1990. Most of the newer partidos were created in the [[Greater Buenos Aires]]. There are 135 partidos, the last established by law is [[Lezama Partido|Lezama]] (2009).

Most of its inhabitants are descendants from colonial-era settlers and immigrants from Europe who arrived within the 19th and 20th centuries, mostly [[Italian people|Italians]] and Spaniards. A number of suburbs in the province are also home to a large, predominantly [[mestizo]] population that began migrating from the country's northern provinces in the mid-20th century to take advantage of growing employment opportunities. These same communities are also home to considerable numbers of more recent migrants from [[Paraguay]] and [[Bolivia]].

==Economy==
[[File:Puertobb.JPG|thumb|Port of [[Bahía Blanca]]]]
The province's economy has long been the largest in Argentina, estimated in 2014 to have been US$407.6 billion (more than a third of the national total, which was around US$680.8 billion in 2016 according to Argentina's economical growing.{{clarify |reason=according to what? |date=August 2012}} It has a per capita income of $24,780 (around $27,300 in 2016). The province is the nation's chief exporter, generating nearly $107 billion in exports in 2016 (37% of the nation's total).<ref>{{cite web |url=http://www.indec.gov.ar/nuevaweb/cuadros/19/ace2008_25.xls |title=INDEC |format=ms xls |language=es |url-status=dead |archive-url=https://web.archive.org/web/20110706083701/http://www.indec.gov.ar/nuevaweb/cuadros/19/ace2008_25.xls |archive-date=6 July 2011}}</ref>

[[File:Junín Campo Cerrito Colorado 20130124 1.jpg|thumb|Soybean fields near [[Junín, Buenos Aires|Junín]]]]
Agriculture in the province is renowned around the world for its productivity. The province is Argentina's chief [[Agriculture in Argentina|agricultural producer]], and accounted for at least $8 billion in export earnings in 2014.<ref name="ecba">{{cite web |url=http://www.ec.gba.gov.ar/Estadistica/FTP/exportacion%202003-06.pdf |title=Exportaciones De La Provincia De Buenos Aires |language=es |url-status=dead |archive-url=https://web.archive.org/web/20080912122239/http://www.ec.gba.gov.ar/Estadistica/FTP/exportacion%202003-06.pdf |archive-date=12 September 2008}}</ref> This sector adds about 5% to the province's highly diversified economy, however.<ref name="ec">{{cite web |url=http://www.ec.gba.gov.ar/Estadistica/FTP/index.html |title=Dirección Provincial De Estadistica |url-status=dead |archive-url=https://web.archive.org/web/20080915162053/http://www.ec.gba.gov.ar/Estadistica/FTP/index.html |archive-date=15 September 2008}}</ref> The province's ranching sector is diversified, and though cattle historically provided the main animal husbandry activity, Buenos Aires is also the top producer of [[sheep]], [[pork]], and [[chicken]] meat of the country. Equally important is the [[dairy]] industry. Crop harvests are the most diverse in the nation and have grown to record levels in recent decades. The most important crops include [[soybean]], [[maize]], [[wheat]], [[sunflower]] and other [[oilseeds]], like [[flax]]. More recently, premium wines have been produced in the [[Buenos Aires wines|Buenos Aires wine]] region in the south of the province.

Manufacturing accounts for a fourth of the province's output and is about 40% of the entire nation's.<ref name="ec" /> The industry of the province is diverse: chemical, pharmaceutical, metallurgic, motor vehicles, machinery, textiles and the food industry are the most notable. Excluding processed agricultural items, the province was responsible for over US$70 billion of industrial exports in 2016 and accounted for a third of all Argentine exports.<ref name="ecba" /><ref>{{cite web |url=http://www.indec.mecon.ar/nuevaweb/cuadros/19/OrigenProv_1sem08.xls |title=INDEC: Foreign trade data |format=ms xls |language=es}}{{dead link|date=April 2016|bot=medic}}{{cbignore|bot=medic}}</ref>

The province's services sector is well-diversified and differs little from national trends. The largest local bank is the public [[Bank of the Province of Buenos Aires]]. The institution, the second largest in Argentina, holds nearly a tenth of the nation's bank deposits.<ref>
