Casimir III the Great reigned as the King of Poland from 1333 to 1370. He also later became King of Ruthenia in 1340, and fought to retain the title in the Galicia-Volhynia Wars. He was the last Polish king from the Piast dynasty.
Jadwiga, also known as Hedwig, was the first woman to be crowned as monarch of the Kingdom of Poland. She reigned from 16 October 1384 until her death. She was the youngest daughter of Louis I of Hungary and Poland, and his wife, Elizabeth of Bosnia. Jadwiga was a member of the Capetian House of Anjou, but she had more close forebears among the Polish Piasts than among the Angevins.
Mary, also known as Maria of Anjou, reigned as Queen of Hungary and Croatia between 1382 and 1385, and from 1386 until her death. She was the daughter of Louis the Great, King of Hungary and Poland, and his wife, Elizabeth of Bosnia. Mary's marriage to Sigismund of Luxembourg, a member of the imperial Luxembourg dynasty, was already decided before her first birthday. A delegation of Polish prelates and lords confirmed her right to succeed her father in Poland in 1379.
The szlachta were the noble estate of the realm in the Kingdom of Poland, the Grand Duchy of Lithuania and the Polish–Lithuanian Commonwealth and, as a social class, dominated those states by exercising political rights and power. Szlachta as a class differed significantly from the feudal nobility of Western Europe. The estate was officially abolished in 1921 by the March Constitution.
Jogaila, later Władysław II Jagiełło, was Grand Duke of Lithuania, later giving the position to his cousin Vytautas in exchange for the title of Supreme Duke of Lithuania (1401–1434) and then King of Poland (1386–1434), first alongside his wife Jadwiga until 1399, and then sole ruler of Poland. Raised a Lithuanian polytheist, he converted to Catholicism in 1386 and was baptized as Ladislaus in Kraków, married the young Queen Jadwiga, and was crowned King of Poland as Władysław II Jagiełło. In 1387, he converted Lithuania to Catholicism. His own reign in Poland started in 1399, upon the death of Queen Jadwiga, lasted a further thirty-five years, and laid the foundation for the centuries-long Polish–Lithuanian union. He was a member of the Jagiellonian dynasty in Poland that bears his name and was previously also known as the Gediminid dynasty in the Grand Duchy of Lithuania. The dynasty ruled both states until 1572, and became one of the most influential dynasties in late medieval and early modern Europe.
Royal elections in Poland were the elections of individual kings, rather than dynasties, to the Polish throne. Based on traditions dating to the very beginning of the Polish statehood, strengthened during the Piast and Jagiellon dynasties, they reached their final form in the Polish–Lithuanian Commonwealth period between 1572 and 1791. The "free election" was abolished by the Constitution of 3 May 1791, which established a constitutional-parliamentary monarchy.
In a strict sense, the Union of Krewo or Act of Krėva comprised a set of prenuptial promises made at Kreva Castle on 14 August 1385 by Jogaila, Grand Duke of Lithuania, in regard to his prospective marriage to the underage reigning Queen Jadwiga of Poland.
The Constitution of the Republic of Poland is the supreme law of the Republic of Poland, which is also commonly called the Third Polish Republic in contrast with the preceding systems.
Elizabeth of Poland was Queen of Hungary by marriage to Charles I of Hungary, and regent of Poland from 1370 to 1376 during the reign of her son Louis I.
Elizabeth of Bosnia was queen consort of Hungary and Croatia, as well as queen consort of Poland, and, after becoming widowed, the regent of Hungary and Croatia between 1382 and 1385 and in 1386.
Vladislaus II of Opole, nicknamed Naderspan, was Duke of Opole from 1356, Count palatine of Hungary (1367–1372), Duke of Wieluń (1370–1392), Governor of Ruthenia (1372–1378), Count palatine of Poland (1378) as well as Duke of Dobrzyń, Inowrocław (1378–1392), Krnov and Kuyavia (1385–1392).
Catherine of Hungary, a member of the Capetian House of Anjou, was heir presumptive to the thrones of Hungary and Poland as eldest child of King Louis the Great and his second wife, Elizabeth of Bosnia.
The period of rule by the Piast dynasty between the 10th and 14th centuries is the first major stage of the history of the Polish state. The dynasty was founded by a series of dukes listed by the chronicler Gall Anonymous in the early 12th century: Siemowit, Lestek and Siemomysł. It was Mieszko I, the son of Siemomysł, who is now considered the proper founder of the Polish state at about 960 AD. The ruling house then remained in power in the Polish lands until 1370. Mieszko converted to Christianity of the Western Latin Church in an event known as the Baptism of Poland in 966, which established a major cultural boundary in Europe based on religion. He also completed a unification of the Lechitic tribal lands that was fundamental to the existence of the new country of Poland.
The rule of the Jagiellonian dynasty in Poland between 1386 and 1572 spans the Late Middle Ages and the Early Modern Period in European history. The Lithuanian Grand Duke Jogaila founded the dynasty; his marriage to Queen Jadwiga of Poland in 1386 strengthened an ongoing Polish–Lithuanian union. The partnership brought vast territories controlled by the Grand Duchy of Lithuania into Poland's sphere of influence and proved beneficial for both the Polish and Lithuanian people, who coexisted and cooperated in one of the largest political entities in Europe for the next four centuries.
The Jagiellonian or Jagellonian dynasty, otherwise the Jagiellon dynasty, the House of Jagiellon, or simply the Jagiellons, was the name assumed by a cadet branch of the Lithuanian ducal dynasty of Gediminids upon reception by Jogaila, the Grand Duke of Lithuania, of baptism as Władysław in 1386, which paved the way to his ensuing marriage to the Queen Regnant Jadwiga of Poland, resulting in his ascension to the Crown of the Kingdom of Poland as Władysław II Jagiełło, and the effective promotion of his branch to a royal dynasty. The Jagiellons were polyglots and per historical evidence Casimir IV Jagiellon and his son Saint Casimir possibly were the last Jagiellons who spoke in their patrilineal ancestors Lithuanian language, however even the last patrilineal Jagiellonian monarch Sigismund II Augustus maintained two separate and equally lavish Lithuanian-speaking and Polish-speaking royal courts in Lithuania's capital Vilnius. The Jagiellons reigned in several European countries between the 14th and 16th centuries. Members of the dynasty were Kings of Poland (1386–1572), Grand Dukes of Lithuania, Kings of Hungary, and Kings of Bohemia and imperial electors (1471–1526).
The privileges of the szlachta formed a cornerstone of "Golden Liberty" in the Kingdom of Poland and, later, in the Polish–Lithuanian Commonwealth (1569-1795). Most szlachta privileges were obtained between the late-14th and early-16th centuries. By the end of that period, the szlachta had succeeded in garnering numerous rights, empowering themselves and limiting the powers of the elective Polish monarchy to an extent unprecedented elsewhere in Europe at the time.
The Privilege of Buda was a set of promises and concessions made to ensure that Louis I of Hungary would succeed to his uncle Casimir III's Polish throne, thus enabling the union of Hungary and Poland.
Personal union between the Kingdom of Hungary and the Kingdom of Poland was achieved twice: under Louis I of Hungary, in 1370–1382, and under Władysław III of Poland in 1440–1444. An earlier union was also accomplished by Wenceslaus III of Bohemia for a few months in 1305, although he was heavily resisted by local nobles in both kingdoms, and gave up the Hungarian crown soon after.
The Greater Poland Civil War refers to the conflict that took place during 1382–1385 in the Greater Poland province of the Kingdom of Poland during the interregnum period following the transition of power between the Piast dynasty, Angevin dynasty and the Jagiellon dynasty.
The Polish vassalization of Moldavia occurred on 26 September 1387 when Petru II of Moldavia paid homage to the King of Poland, Władysław II Jagiełło, at Lwów, making the Principality of Moldavia a vassal state of the Crown of the Kingdom of Poland.
