The coronation of Birger Jarlsson Valdemar took place in the cathedral in 1251; and in the reign of Gustavus Vasa several important diets were held in the town.
At the two Diets held by him, at Kassa and Talya, in 1683, the estates, though not uninfluenced by his personal charm, showed some want of confidence in him, fearing lest he might sacrifice the national independence to the Turkish alliance.
The united diet which was opened on the 3rd of February 1847 was no more than a congregation of the diets instituted by Frederick William III.
His proposals came to nothing, but he continued the struggle at a series of diets, and urged the Germans to emulate the courage and union of the Swiss cantons.
Sigismund, more fortunate than the Polish kings, seems to have had little trouble with his diets.
