When in 928 King [[Henry the Fowler|Henry I of Germany]] crossed the [[Elbe]] river to conquer the lands of the Veleti, he did not subdue the Leubuzzi people settling beyond the [[Spree (river)|Spree]]. Their territory was either already inherited by the first Polish ruler [[Mieszko I of Poland|Mieszko I]] (~960-992) or conquered by him in the early period of his rule. After Mieszkos' death the whole country was inherited by his son Duke, and later King, [[Bolesław I the Brave]]. After the German [[Northern March]] got lost in a 983 Slavic rebellion, Duke Bolesław and King [[Otto III, Holy Roman Emperor|Otto III of Germany]] in 991 agreed at [[Quedlinburg]] to jointly conquer the remaining [[Lutici]]an territory, Otto coming from the west and Bolesław starting from Lubusz in the east. However, they did not succeed. Instead Otto's successor King [[Henry II, Holy Roman Emperor|Henry II of Germany]] in the rising conflict over the adjacent [[March of Lusatia|Lusatian march]] concluded an alliance with the Lutici and repeatedly attacked Bolesław.

Lubusz Land remained under Polish control even after King [[Mieszko II Lambert]] in 1031 finally had to withdraw from the adjacent, just conquered March of Lusatia and accept the overlordship of Emperor [[Conrad II, Holy Roman Emperor|Conrad II]]. In 1125 Duke [[Bolesław III Wrymouth]] of Poland established the [[Bishopric of Lubusz]] to secure Lubusz Land. 1124-1125 records note that the new Bishop of Lubusz was nominated by Duke Bolesław under the [[Archbishops of Gniezno and Primates of Poland|Archbishopric of Gniezno]]. However, from the beginning Gniezno's role as metropolia of the Lubusz diocese was challenged by the claims of the mighty [[Archbishopric of Magdeburg|Archbishops of Magdeburg]], who also tried to make Lebus their suffragan. The Polish position was decisively enfeebled by the process of [[History of Poland (966–1385)|fragmentation]] after the death of Duke Bolesław III in 1138, when Lubusz Land became part of the [[Duchy of Silesia]].<ref>{{Cite book|last=Zientara|first=Benedykt|title=Henryk Brodaty i jego czasy|publisher=Trio|year=2006|isbn=83-7436-056-9|pages=193–96|language=pl}}</ref> The Duchy of Silesia was restored to the descendants of [[Władysław II the Exile]] in 1163, and Lubusz Land together with [[Lower Silesia]] was given to his eldest son [[Bolesław I the Tall]].

In the 13th century Polish dukes in order to help develop Lubusz Land, granted some areas to different [[Religious order (Catholic)|Catholic religious orders]], such as the [[Cistercians]], Canons Regular and [[Knights Templar]]. Among those orders possessions were [[Łagów, Świebodzin County|Łagów]], [[Chwarszczany]], [[Müncheberg|Lubiąż]] (today's ''Müncheberg'') and [[Dębno]].<ref>''Codex diplomaticus Majoris Polonia'', tom XI</ref>

Lubusz remained under the rule of the [[Silesian Piasts]], though Bolesław's son Duke [[Henry I the Bearded]] in 1206 signed an agreement with Duke [[Władysław III Spindleshanks]] of [[Greater Poland]] to swap it for the [[Kalisz Region]]. This agreement however did not last as it provoked the revolt of Władysław's nephew [[Władysław Odonic]], while in addition the [[March of Lusatia|Lusatian]] margrave Conrad II of Landsberg took this occasion to invade Lubusz. Duke Henry I appealed to Emperor [[Otto IV, Holy Roman Emperor|Otto IV]] and already started an armed expedition, until he was once again able to secure his possession of the region after Margrave Conrad had died in 1210. Nevertheless, the resistance against the Imperial expansion waned as the Silesian territories were again fragmented after the death of Duke [[Henry II the Pious]] at the [[Battle of Legnica]] in 1241. His younger son [[Mieszko, Duke of Lubusz|Mieszko]] then held the title of a "[[Duchy of Lubusz|Duke of Lubusz]]", but died only one year later, after which his territory fell to his elder brother [[Bolesław II the Bald]]. In 1248 Bolesław II, then [[Duchy of Legnica|Duke of Legnica]], finally sold Lubusz to Magdeburg's Archbishop Wilbrand von Käfernburg and the [[House of Ascania|Ascanian]] margraves of Brandenburg in 1249, wielding the secular reign.
