text: Although the Tripartituma frequently cited compilation of customary law published in 1514reinforced the idea that all noblemen were equal, the monarchs granted hereditary titles to powerful aristocrats, and the poorest nobles lost their tax exemption from the mid-16th century. In the early modern period, because of the expansion of the Ottoman Empire, Hungary was divided into three parts: Royal Hungary, Transylvania and Ottoman Hungary. The princes of Transylvania supported the noblemen's fight against the Habsburg dynasty in Royal Hungary, but prevented the Transylvanian noblemen from challenging their own authority. Ennoblement of whole groups of people was not unusual in the 17th century. Examples include the 10,000  who received nobility as a group in 1605. After the Diet was divided into two chambers in Royal Hungary in 1608, noblemen with a hereditary title had a seat in the upper house, other nobles sent delegates to the lower house.
  After the Ottomans' defeat in the Great Turkish War in the late 17th century, Transylvania and Ottoman Hungary were integrated into the Habsburg monarchy. The Habsburgs confirmed the nobles' privileges several times, but their attempts to strengthen royal authority regularly brought them into conflicts with the nobility, who represented nearly five percent of the population. Reformist noblemen demanded the abolition of noble privileges from the 1790s, but their program was enacted only during the Hungarian Revolution of 1848. Most noblemen lost their estates after the emancipation of their serfs, but the aristocrats preserved their distinguished social status. State administration employed thousands of impoverished noblemen in Austria-Hungary. Prominent (mainly Jewish) bankers and industrialists were awarded with nobility, but their social status remained inferior to traditional aristocrats. Noble titles were abolished only in 1947, months after Hungary was proclaimed a republic.
