Banat, Crişana, and Transylvania were integrated into the Kingdom of Hungary in the 11th century. These regions were subject to plundering raids by the nomadic Pechenegs and Cumans, who dominated the lowlands east of the mountains. Hungarian monarchs promoted the immigration of Western European colonists to Transylvania from the 1150s. The colonists' descendants, who were known as Transylvanian Saxons from the early 13th century, received collective privileges in 1224. Because of the settlement of the Saxons in their former territories, the Székelys were moved to the easternmost zones of the kingdom. The emergence of the Mongol Empire in the Eurasian Steppes in the first decades of the 13th century had lasting effects on the history of the region. The Mongols subjugated the Cumans in the 1230s and destroyed many settlements throughout the Kingdom of Hungary in 1241 and 1242, bringing the Early Middle Ages to an end.
