A Sejm Postponed. The Sejm in Warsaw. 1556-1557.
The execution Sejm announced by the King and planned for August was ultimately convoked for December 6th 1556 (St. Nicholas’ Day) as an ordinary assembly. Pre-Sejm Sejmiks convened in November. Upon request by King Sigismund Augustus who promised to convoke a separate execution Sejm, deputies agreed to focus on current affairs, matters of defence in particular, especially for the sake of Lithuania suffering threat along the Livonian borders. Matters of execution of rights and assets and of reorganising the judiciary were postponed for consideration by another Sejm, to be attended by deputies of the Grand Duchy of Lithuania, Royal Prussia, and the Duchies of Oświęcim and Zator. The Sejm concluded on January 14th 1557.
