Diet of Hungary

The Diet of Hungary or originally: Parlamentum Publicum / Parlamentum Generalye (Hungarian: Országgyűlés) was a legislative institution in the medieval kingdom of Hungary from the 1290s, and in its successor states, Royal Hungary and the Habsburg kingdom of Hungary throughout the Early Modern period. The name of the legislative body was originally "Parlamentum" during the Middle Ages, the "Diet" expression gained mostly in the Early Modern period. It convened at regular intervals with interruptions during the period of 1527 to 1918, and again until 1946.

The articles of the 1790 diet set out that the diet should meet at least once every 3 years, but, since the diet was called by the Habsburg monarchy, this promise was not kept on several occasions thereafter. As a result of the Austro-Hungarian Compromise, it was reconstituted in 1867.

The Latin term Natio Hungarica ("Hungarian nation") was used to designate the political elite which had participation in the diet, consisting of the nobility, the Catholic clergy, and a few enfranchised burghers, regardless of language or ethnicity. Natio Hungarica was a geographic, institutional and juridico-political category.

Some researchers have traced the roots of the Hungarian institution of national assemblies as far back as the 11th century. This based on documentary evidence that, on certain occasions under the reigns of King Ladislaus I and King Coloman “the Book lover”, assemblies were held on a national scale where both ecclesiastic and secular dignitaries made appearances. The first written mention of Hungarian Parliament originated under King Andrew II with the Golden Bull of 1222, which reaffirmed the rights of the smaller nobles of the old and new classes of royal servants (servientes regis) against both the crown and the magnates, and to defend the rights of the whole nation against the crown by restricting the powers of the latter in certain fields and legalizing refusal to obey its unlawful/unconstitutional commands (the "ius resistendi"). The lesser nobles also began to present Andrew with grievances, a practice that evolved into the institution of the Hungarian Diet.
