Crown of the Kingdom of Poland , 1535, painting by
Jan Matejko 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 for state defence. However, he was unsuccessful in 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. Likely related to tax matters was an unsuccessful attempt on the life of the king, made on 5 May 1523. The identity of the would-be assassin - who shot the ruler while he was strolling in the evening around the cloisters of the
Wawel castle - and his potential supporters was never established. Unclear motives remained after the assassination attempt. Three weeks before the event, Sigismund I introduced a new edict that was very unfavourable and somewhat hostile to the high-ranking nobles and their interests. Sigismund I achieved several economic successes, including partial debt reduction, the separation of accounts of public taxation from the royal treasury, the strengthening of the activities of the mint operating in Kraków, and the attempt to organise the processing of income from operating salt mines. Furthermore, he issued a statute for the
Armenians (1519) and strongly intended to harmonise the judicial system across the country. Between 1530 and 1538, the king issued two statutes defining the rules for the selection of the monarch, which permanently established the election
viritim. The laws held that all social groups, regardless of their wealth, could watch the election process (
unusquisque qui vellet), and the election was to be free (
electio Regis libera). Sigismund successfully organised the agricultural economy, looked after the development of the royal cities and recovered numerous goods of the treasury belonging to the crown that were under lien. During the financial activities, the King received full support of his wife, Queen Bona, who aimed to expand the royal estates by purchasing and improving economic efficiency. In 1514, he set up the
Council of Four Lands and put
Abraham of Bohemia in charge of it. Sigismund I vested various localities with

Chicken War Rebellion . Seated Sigismund is accompanied by his wife
Bona Sforza and royal court whilst being surrounded by an angry mob at
Lwów High Castle At the start of his reign, King Sigismund I the Old inherited a Kingdom of Poland with a century-long tradition of liberties of the nobility, confirmed in numerous privileges. A rebellion in
Lwów widely known as the
Chicken War () was an anti-royalist and anti-absolutist
rokosz (revolt) by the Polish nobility that occurred in 1537. The derisive name was coined by the magnates, who for the most part supported the King and claimed that the "war's" only effect was the near-extinction of the local chickens, eaten by the nobles gathered for the rebellion at Lwów in eastern part of
Lesser Poland. To strengthen his power, Sigismund initiated a set of reforms, establishing a permanent conscription army in 1527 and extending the bureaucratic apparatus necessary to govern the state and finance the army. Supported by his Italian consort Bona Sforza, he began buying up land and issue agriculture reformas to enlarge the royal treasury. He initiated a process of restitution of royal properties, previously pawned or rented to the nobles. The nobility gathered near the city to meet in a
levée en masse and called for a military campaign against
Moldavia. However, the lesser and middle strata of the nobility organised a revolt to force the King to abandon his risky reforms. The nobles presented him with 36 demands, most notably a cessation of further land acquisitions by Queen Bona, exemption of the nobility from the
tithe, confirmation and extension of privileges for nobles and adoption of a law concerning
Incompatibilitas — an individual wouldn't be able to hold two or more official administrative positions in the country. The role of the Incompatibilitas was to prevent wealthy
magnates from usurping too much power at the expense of lesser nobles. However, the revolt soon transpired that the nobility's leaders were divided and that achieving a settlement was almost impossible. Too weak to start a civil war against the King, the protesters finally agreed to what was thought to be a compromise. Sigismund rejected most of their demands, while accepting the principle of Incompatibilitas the following year and agreeing not to force the election of the future king in
vivente rege. Thereupon, the nobility returned to their homes, having achieved little. == Foreign politics ==
