The Golden Bull of 1222 was a significant charter issued by King Andrew II of Hungary. It established the rights and privileges of the nobility in Hungary, marking a crucial step in the development of the country's legal framework. The document aimed to limit the king's power and protect the interests of the nobles, ensuring their participation in governance. This charter is often considered one of the earliest examples of constitutional law in Hungary. It outlined various rights, including the nobility's right to assemble and the protection of their properties, thereby laying the groundwork for future legal reforms in the region.
