The Congress of Wolbórz was a groundbreaking political event in 1241, during which the Piast princes made crucial decisions regarding the defense of the country against the approaching Mongol invasion. The meeting took place in Wolbórz, the seat of the Kuyavian bishops.

The Congress of Wolbórz was one of the most important political events of medieval Poland that took place in 1241. This historic meeting was held in the small town of Wolbórz located in central Poland and gathered the most important representatives of the authorities at the time.

In the face of the approaching Mongol invasion, the Piast princes had to make key decisions regarding the country's defense. The congress convened by Konrad of Masovia aimed to unite forces and develop a common defensive strategy. It was during this event that important decisions were made that influenced Poland's fate during the Mongol invasion.

The Congress of Wolbórz took place at a crucial moment for medieval Poland, during a period of growing threat from the Mongols. The political situation of the 13th century forced rulers to take quick and decisive defensive actions.

Poland in the 13th century was characterized by significant feudal fragmentation, with many competing centers of power. Here are the main elements of the political situation at that time:

• Rivalry between provinces for supremacy over other lands

• Conflicts between Konrad of Masovia and Henry the Bearded over the guardianship of young Bolesław V the Chaste

• Threat from the Prussians in the north

• Expansion of the Teutonic Order in Polish lands since 1226

• Growing tensions on the eastern borders of the state

• Wolbórz was owned by the Kuyavian bishops, which gave it a neutral character

• Bishops acted as mediators in disputes between princes

• Church hierarchs held extensive political influence through:

• Management of vast landed estates

• Control over education

• Maintaining international contacts

• The Church organized a defense system against invasions through:

• Using monastery networks as information points

• Mobilizing knights at bishops' call

• Gathering resources for defensive purposes

Aspect of Church Authority	Scope of Influence
Landed estates	15% of state territory
Monastic centers	25 major complexes
Parish network	800 parishes

The Assembly in Wolbórz in 1214 gathered the most important representatives of secular and church authority in the Kingdom of Poland. The meeting took place at the seat of Kuyavian bishops, where key state and church matters were discussed.

The Wolbórz Assembly marked a turning point in the history of the Piast state. This event influenced the shaping of relations between secular and church authorities and changed the balance of political power in the fragmented kingdom.

The Wolbórz Assembly led to strengthening the Church's position within the Piast state structures. Bishops received judicial immunity exempting church properties from princely jurisdiction. Cathedral chapters gained the right to independently elect bishops without secular authority interference. The Church obtained exemption from princely law burdens such as: guard duty, transport service, and carriage service.

The agreement reached during the assembly led to temporary mitigation of conflicts between regional princes. The assembly's resolutions changed the state management system through:

• Introduction of new division of competencies between secular and church authorities

• Establishment of principles for princely power succession

• Reorganization of the judiciary system in Polish lands

• Regulation of tribute and tax matters

• Princely chancellery

• Land courts

• Treasury offices

• Territorial administration system

Wolborz occupied a central position on the map of medieval Poland, at the intersection of trade routes from Krakow to Torun and from Mazovia to Silesia. The city had an extensive fortification system, including a 12th-century bishop's castle. The strategic advantages of Wolborz included:

• Access to the Moszczanka River, providing natural protection
