The Diet of Hungary or originally: Parlamentum Publicum / Parlamentum GeneraleAndrás Gergely, Gábor Máthé: The Hungarian state: thousand years in Europe (published in 2000) () was the most important political assembly in Hungary since the 11th century, which emerged to the position of the supreme legislative institution in the Kingdom of Hungary from the 1290s,Elemér Hantos: The Magna Carta of the English And of the Hungarian Constitution (1904) and in its successor states, Royal Hungary and the Habsburg kingdom of Hungary throughout the early modern period until the end of World War II. The name of the legislative body was originally "Parlamentum" during the Middle Ages, the "Diet" expression gained mostly in the early modern period.Cecil Marcus Knatchbull-Hugessen Brabourne (4th Baron): The political evolution of the Hungarian nation: (Volume I. in 1908) It convened at regular intervals with interruptions from the 12th century 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 elite which had participation in the medieval and early modern era political life of Hungary (at local level as members of the assemblies of the counties, or nation-wide level as members of the Parliaments). The members of the parliament consisted of the envoys of the Roman Catholic clergy, the elected envoys of the nobility from the county assemblies of the Kingdom, and the envoys of cities who were elected by the people of the Royal Free CitiesJohn M.

Official Designations Medieval era Throughout the Middle Ages, the most frequently employed Latin designation for internal use was Congregatio Generalis, (English: “general assembly.”) From the late 12th century until the early 16th century, Congregatio Generalis remained the predominant term appearing exclusively in Latin-language documents intended for domestic official purposes, serving as the recognized designation of the Hungarian estates’ assemblies.

Although extremely rare for domestic purposes, the terms Parlamentum Publicum and Parlamentum Generale were in use from the very outset. However, the usage of Parlamentum was dominant name and almost exclusively confined to diplomatic correspondence or communications intended for foreign audiences, in order to provide a more readily comprehensible terminology familiar to Western Europe.

Early modern period The early modern era designation, Diéta, which came into prominence from the Jagellonian period onward, is likewise of Latin origin—classically, diaeta signified “daily regimen, assembly, or mode of life.” However, the term Dieta entered the Hungarian legal lexicon through German influence and mediation, deriving from the practices of the Holy Roman Empire, where it appeared as the "Reichstag Diät".

The Latin-language German imperial documents frequently employed the term dietas imperiales (“imperial assemblies”), while in German-language sources the compound "Reichstag Diät" was commonly used. Variants included Kurfürstliche Diät—assemblies of the German prince-electors or regional estates —and Stände- or Landdiät— provincial or local German assemblies, attended, for example, by the German nobility and towns of a given territory.

Thus, in Jagellonian Hungary, the Dieta did not assume official status as a direct continuation of its classical Latin origin, but rather as a Latin term adapted from the legacy of German imperial model.

Concurrently, during the Jagellonian period, the Hungarian-language term országgyűlés (“national assembly”) began to appear and gradually spread in early Hungarian correspondence and documentary sources alongside the Latin-German origin Dieta.

Development

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 "important occasions" under the reigns of King Ladislaus I and King Coloman "the Learned", assemblies were held on a national scale where both ecclesiastic and secular dignitaries made appearances.Dr. Zoltán SZENTE: The Historic Origins of the National Assembly in Hungary| The first exact written mention of the word "parlamentum" (parliament) for the nationwide assembly originated during the reign of King Andrew II in 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.

An institutionalized Hungarian parliament emerged during the 14th and 15th centuries. Beginning under King Charles I and continuing under subsequent kings through into the reign of King Matthias I, the Diet was primarily convened by the king. However, under the rule of autocratic kings like Louis the Great and the early absolutist Matthias Corvinus, parliaments were often summoned merely to formalize royal decisions, which members were obliged to approve to meet constitutional requirements, thus it had no significant power of its own. However, since the reign of the Jagiellonian dynasty, the parliament has regained most of its traditional power.

In 1492, the Diet limited all serfs' freedom of movement and greatly expanded their obligations while at the same time only a few peasant families were prospering because of increased cattle exports to the West. Rural discontent boiled over in 1514 when well-armed peasants preparing for a crusade against Turks rose up under György Dózsa. Shocked by the peasant revolt, the Diet of 1514 passed laws that condemned the serfs to eternal bondage and increased their work obligations further.

When King Vladislaus II died in 1516, a royal council appointed by the Diet ruled the country in the name of his ten-year-old son, King Louis II (1516–26).

In 1608 the Diet divided into two houses: House of Magnates and House of Representatives. From next Diet in 1609, the members of the House of Representatives elected by nobles of the Counties, by civics of the free royal cities and by members of the cathedral chapters.

Diet of the Estates Until 1848, the Diets were called Hungarian Diet of the Estates (Hungarian: Rendi országgyűlés) which was an Estates General.

From the 13th century onwards, law-making was a joint right of the king and the diet. This remained a fundamental principle of the constitution of the later society of estate. After the extinction of the House of Árpád, the king was in many cases elected by the Diet, which guaranteed the Szabad Királyválasztás Joga (right of electing the king).

Before the development of the society of estate, the Diet consisted of the lords and the leaders of the church, but then the voting base was extended to the common nobility and the elected representatives of Royal free cities. By the 16th century the social classes that made up the 4 estates were the nobility, the common nobility, the clergy and the burghers.

From the 1400s onwards, two chambers began to be steadily separated, the lower plate of the estates and the arch-noblety on the upper. With the parliamentary system, the upper chamber was given over to the high priests and arch-nobles, while the lower chamber was filled by elected representatives. The Era of Reforms in 1848 brought an end to the Diet of the Estates, introducing the National Assembly. One of the key words of the Revolution of '48 was the taking away the privileges of the nobles and oligarchs, so currently there is an unicameral system, to guarantee the rule of the people. Until 1848, cathedral chapters were also members of the lower house, with 1-2 envoys.
