The internal situation in Poland was characterised by broad authorisation of the Chamber of Deputies, confirmed and extended in the constitution of "Nihil novi". During Alexander's reign, the law of "Nihil novi" had been instituted, which forbade kings of Poland from enacting laws without the consent of the Sejm. Sigismund had little control over the act, unlike the senators, whom he personally appointed. Eventually, during his reign, Sigismund benefited from the advice of the local nobility, competent ministers in charge of the royal judiciary system, and the wealthy influential treasurers of Kraków. Although he was reluctant to the parliamentary system and political independence of the nobility, he recognised the authority of legal norms, supported legalism and summoned annual sessions of the Sejm, usually obtaining funds on state defence. However he was unsuccessful at attempting to create a permanent fund for defence from the annual income tax. Despite this, in 1527 he established a conscript army and the bureaucracy needed to finance it. He set up the legal codes that formalised serfdom in Poland, placing the peasants into the private estates of nobles.
