Golden Liberty
In the Jagiellonian period, Poland developed as a feudal state with a predominantly agricultural economy and an increasingly dominant landed nobility. The "Nihil novi" act adopted by the Polish Sejm in 1505 transferred most of the legislative power in the state from the monarch to the Sejm. This event marked the beginning of the period known as "Golden Liberty", when the state was ruled by the "free and equal" members of the Polish nobility.
