Editing Durango (section)

===19th century===
During [[Mexican War of Independence|Mexico's War of Independence]], Nuevo Vizcaya began to break up. The first divisions were the creation of the states of Chihuahua and Durango, with Santiago Baca Ortiz as the first governor of the state of Durango along with the separation of the Sinaloa province, which included Sonora and Arizona.  The state of Coahuila was separated shortly thereafter. With the 1824 Constitution the states of Durango and Chihuahua were created.<ref name=":2" /> Mining was depressed at the time, and the governor negotiated with the English to explore deposits of iron on the Cerro de Mercado. The English constructed installations such as those in Piedras Azules (La Ferrería) to process iron ore. These required large quantities of charcoal, which led to mass deforestation in the area.<ref name=":0" /> This eventually made the plant unviable.<ref name=":1" />

Public education was first established in the state in 1824. The first secular institute of higher education in the state was the Colegio Civil y la Academia de Juisprudencia founded in 1833.<ref name=":2" />

The northeast of the state had problems industrializing mostly due to incursions by Apaches into Durango which began in 1832 and later Comanches. Attacks by Comanches remain a major problem until the 1850s, forcing haciendas and textile mills to build walls around them.  Counter-attacks on the Comanches diminished their raids, but they did not stop completely until the 1880s.<ref name=":1" />

The rise of the state's second economic and political center, the cities of Gómez Palacio and Lerdo began in the 19th century, when cotton began to be planted along the Nazcas River. This cotton production became important, with sales of the raw material to Mexico City and to European textile mills, especially in England. Large-scale production began in the mid-century, dominating the local economy by the 1870s. Textile production also began here, although shortly after this industry would shift to Torreon.<ref name=mwolfe/> Other textile mills were established in areas such as Tunal, Santiago Papasquiaro, Poanas and Peñon Blanco, but the lack of coal meant that power had to be provided by nearby rivers, which was not efficient enough. This and attacks during the Mexican Revolution brought the demise of the textile industry in the state. Many mills and cotton haciendas eventually wound up in the hands of American investors.<ref name=":0" />

The civil war between liberals and conservatives had the state controlled by liberal forces in 1858, then by conservative ones from 1864 to 1866.<ref name=":2" />

In the late 19th century, rail and telegraph lines reached the state and revitalized Gómez Palacio and Lerdo as industrial centers. The railroad connected the city of Durango with Mexico City and the US border, allowing for shipment of local goods, particularly those from mining, to national and foreign markets. Agriculture and livestock production increased with the end of Comanche insurgencies and the arrival of a train line in 1892 gave the city a new connection with the rest of Mexico. It directly connected the city with Piedras Negras, Coahuila allowing the export of iron ore to foundries in Monclova, where coal was abundant. In 1902, a branch of the railroad reached Tepehuanes, allowing for the exploitation of natural resources in the northwest of the state.<ref name=":0" /><ref name=":2" />

However, the city of Durango remained the political center of the state as well as the regional commercial center for agricultural and handcrafted products. Mayors of the city at this time concentrated on improving infrastructure, such as government buildings, hospitals, water supply lines and public streets. The population of the city grew during this time.<ref name=":0" />
