Defence and budget. Sejm in Piotrków, 1533.
The sejm was called by king Sigismund I on 23 October 1532 to be held on 6 January 1533 in Piotrków. The pre-sejm sejmiks lasted from 22 November to 13 December 1532. The sejm debated from 20 January to 14 April 1533. The subject of the debate, except tax matters, was to be the confirmation of the law rectification, that is codification of Polish law, prepared by a law rectification committee. Because the provincial sejmiks did not end revising the planned codification of law, ordered by the regulation of sejm in 1532, the law rectification matter was not even discussed. The sessions were predominantly dedicated to debating the national defence and taxes and military wages, related to the topic.
