After 1244, Stephen Báncsa sought to strengthen the authority of the Metropolitan Archdiocese over the chapters and monastic orders in Hungary. His most important mainstay was Pope Innocent in these endeavors. For instance, Albert, provost of Arad was forced to acknowledge the supremacy of Esztergom over his chapter in 1246. Pope Innocent ordered the monks of the Mount of Saint Martin (Pannonhalma) to promise obedience to the Archdiocese of Esztergom as their exarchate in 1247. When Béla confirmed the privileges of the hospes in Beregszász (today Berehove, Ukraine) in December 1247, the king assigned the jurisdiction of Esztergom to the Saxon community. The Premonstratensian provostry of Hatvan was also a subject of the archdiocese's spiritual jurisdiction. The acquired area was settled with colonists by Báncsa since the early 1240s. Báncsa expanded the archbishopric' landed property with purchases, exchanges and donations. He donated the tithe of wine production to the canons of the St. Adalbert Cathedral in 1244. Upon his request, Nicholas, custos of Esztergom and dean of Sasvár (today part of Šaštín-Stráže, Slovakia) and the Esztergom Chapter were granted the estates of Szőlő and Rendvég (belonged to Nógrád Castle) by Béla IV in 1248. Báncsa donated the land of Tyrna to the collegiate chapter in 1250.
