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. Born 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.
Vytautas, also known as Vytautas the Great from the late 14th century onwards, was a ruler of the Grand Duchy of Lithuania. He was also the prince of Grodno (1370–1382), prince of Lutsk (1387–1389), and the postulated king of the Hussites.
Švitrigaila was the Grand Duke of Lithuania from 1430 to 1432. He spent most of his life in largely unsuccessful dynastic struggles against his cousins Vytautas and Sigismund Kęstutaitis.
The (First) Peace of Thorn was a peace treaty formally ending the Polish–Lithuanian–Teutonic War between allied Kingdom of Poland and Grand Duchy of Lithuania on one side, and the Teutonic Knights on the other. It was signed on 1 February 1411 in Thorn (Toruń), one of the southernmost cities of the Monastic State of the Teutonic Knights. In historiography, the treaty is often portrayed as a diplomatic failure of Poland–Lithuania as they failed to capitalize on the decisive defeat of the Knights in the Battle of Grunwald in June 1410. The Knights returned Dobrzyń Land which they captured from Poland during the war and made only temporary territorial concessions in Samogitia, which returned to Lithuania only for the lifetimes of Polish King Władysław Jagiełło and Lithuanian Grand Duke Vytautas. The Peace of Thorn was not stable. It took two other brief wars, the Hunger War in 1414 and Gollub War in 1422, to sign the Treaty of Melno that solved the territorial disputes. However, large war reparations were a significant financial burden on the Knights, causing internal unrest and economic decline. The Teutonic Knights never recovered their former might.
This is the 1409-1411 Polish-Lithuanian-Teutonic War. For a list of all Polish-German Wars, see Polish-German Wars.
Heinrich von Plauen (the Elder) (ca. 1370–1429) was the 27th Grand Master of the Teutonic Knights, serving from November 1410 to October 1413. Having becoming grandmaster in the wake of the Battle of Grunwald, he was a stern proponent of prolonging the war with Lithuania and Poland. Because all male members of his family were baptized as Heinrich (Henry), he is sometimes known as Heinrich von Plauen the Elder to differentiate from his relative, Heinrich von Plauen the Younger (died ca. 1441).
The Treaty of Melno or Treaty of Lake Melno was a peace treaty ending the Gollub War. It was signed on 27 September 1422, between the Teutonic Knights and an alliance of the Kingdom of Poland and the Grand Duchy of Lithuania at Lake Melno, east of Graudenz (Grudziądz). The treaty resolved territorial disputes between the Knights and Lithuania regarding Lithuania Minor and Samogitia, which had dragged on since 1382, and determined the Prussian–Lithuanian border, which afterwards remained unchanged for about 500 years. A portion of the original border survives as a portion of the modern border between the Republic of Lithuania and Kaliningrad Oblast, Russia, making it one of the oldest and most stable borders in Europe.
The Battle of Wiłkomierz took place on September 1, 1435, near Ukmergė in the Grand Duchy of Lithuania. With the help of military units from the Kingdom of Poland, the forces of Grand Duke Sigismund Kęstutaitis soundly defeated Švitrigaila and his Livonian allies. The battle was a decisive engagement of the Lithuanian Civil War (1432–1438). Švitrigaila lost most of his supporters and withdrew to southern Grand Duchy; he was slowly pushed out and eventually made peace. The damage inflicted upon the Livonian Order has been compared to the damage of Battle of Grunwald upon the Teutonic Order. It was fundamentally weakened and ceased to play a major role in Lithuanian affairs. The battle can be seen as the final engagement of the Lithuanian Crusade.
This is the 1414 Polish-Teutonic War. For a list of all Polish-German Wars, see Polish-German Wars.
Polish–Teutonic Wars refer to a series of conflicts that took place between the Kingdom of Poland and the Teutonic Order, a medieval German military order with roots in the Baltic region. These wars occurred primarily during the 14th and 15th centuries and were characterized by territorial disputes, political maneuvering, and religious differences.
The Lithuanian Civil War of 1432–1438 was a war of succession to the throne of the Grand Duchy of Lithuania, after Vytautas the Great died in 1430 without leaving an heir. The war was fought on the one side by Švitrigaila, allied with the Teutonic Knights, and on the other by Sigismund Kęstutaitis, backed by the Kingdom of Poland. The war threatened to sever the Union of Krewo, the personal union between Poland and Lithuania. Švitrigaila's alliance with the Grand Master of the Teutonic Order, Paul von Rusdorf, launched the Polish–Teutonic War (1431–1435) but failed to secure victory for Švitrigaila.
The Ostrów or Astrava Agreement was a treaty between Jogaila, King of Poland and Grand Duke of Lithuania, and his cousin Vytautas the Great, signed on 4 August 1392. The treaty ended the destructive Lithuanian Civil War, launched in 1389 by Vytautas who hoped to gain political power, and concluded the power struggle between the two cousins that erupted in 1380 after Jogaila secretly signed the Treaty of Dovydiškės with the Teutonic Knights. The Ostrów Agreement did not stop attacks from the Teutonic Knights and the territorial dispute over Samogitia continued up to 1422. According to the treaty, Vytautas became the ruler of Lithuania, but he also acknowledged Jogaila's rights to Lithuania. The details of the Polish–Lithuanian relationship were clarified in several later treaties, including the Union of Vilnius and Radom in 1401 and Union of Horodło in 1413.
The Treaty of Salynas was a peace treaty signed on 12 October 1398 by Vytautas the Great, the Grand Duke of Lithuania, and Konrad von Jungingen, the Grand Master of the Teutonic Knights. It was signed on an islet of the Neman River, probably between Kulautuva and the mouth of the Nevėžis River. It was the third time, after the Treaty of Königsberg (1384) and Treaty of Lyck (1390), that Vytautas promised Samogitia to the Knights. The territory was important to the Knights as it physically separated the Teutonic Knights in Prussia from its branch in Livonia. It was the first time that the Knights and Vytautas attempted to enforce the cession of Samogitia. However, it did not solve the territorial disputes over Samogitia and they dragged on until the Treaty of Melno in 1422.
The Treaty of Lyck was a treaty between Vytautas the Great, future Grand Duke of Lithuania, and the Teutonic Knights, represented by Marquard von Salzbach, komtur Arnold von Bürglen, and Thomas, son of Lithuanian duke Survila. It was signed on 19 January 1390 in Lyck, State of the Teutonic Order,. Vytautas, in exchange for a military alliance against his cousin Jogaila during the Lithuanian Civil War (1389–1392), agreed to cede Samogitia up to the Nevėžis River and become the Order's vassal. In essence Vytautas confirmed the Treaty of Königsberg (1384) that he had signed with the Knights during the Lithuanian Civil War (1381–1384). Once betrayed, the Knights now asked for hostages as a guarantee of Vytautas' loyalty. The Order demanded as hostages his two brothers Sigismund and Tautvilas, wife Anna, daughter Sophia, sister Rymgajla, brother-in-law Ivan Olshanski, and a number of other nobles.
Samogitian uprisings refer to two uprisings by the Samogitians against the Teutonic Knights in 1401–1404 and 1409. Samogitia was granted to the Teutonic Knights by Vytautas the Great, Grand Duke of Lithuania, several times in order to enlist Knights' support for his other military affairs. The local population resisted Teutonic rule and asked Vytautas to protect them. The first uprising was unsuccessful and Vytautas had to reconfirm his previous promises to transfer Samogitia in the Peace of Raciąż. The second uprising provoked the Knights to declare war on Poland. Hostilities escalated and resulted in the Battle of Grunwald (1410), one of the biggest battles of medieval Europe. The Knights were soundly defeated by the joint Polish–Lithuanian forces, but Vytautas and Jogaila, King of Poland, were unable to capitalize on their victory. Conflicts regarding Samogitia, both diplomatic and military, dragged until the Treaty of Melno (1422).
The Battle of Grunwald, Battle of Žalgiris, or First Battle of Tannenberg, was fought on 15 July 1410 during the Polish–Lithuanian–Teutonic War. The alliance of the Crown of the Kingdom of Poland and the Grand Duchy of Lithuania, led respectively by King Władysław II Jagiełło (Jogaila), and Grand Duke Vytautas, decisively defeated the German Teutonic Order, led by Grand Master Ulrich von Jungingen. Most of the Teutonic Order's leadership was killed or taken prisoner.
This is the 1431-1435 Polish-Teutonic War. For a list of all Polish-German Wars, see Polish-German Wars.
The Treaty of Christmemel was a treaty signed on 19 June 1431 between Paul von Rusdorf, Grand Master the Teutonic Knights, and Švitrigaila, Grand Duke of Lithuania. Švitrigaila was preparing for a war with Poland to defend his claim to the Lithuanian throne and sought allies. The treaty established an anti-Polish alliance and prompted the Knights to invade the Kingdom of Poland, starting the Polish–Teutonic War (1431–35). Lithuania also surrendered Palanga and three miles of the coastline on the Baltic Sea, thus modifying the Treaty of Melno of 1422.
The Lithuanian Crusade was a series of campaigns by the Teutonic Order and the Livonian Order under the pretext of forcibly Christianizing the pagan Grand Duchy of Lithuania. The Livonian Order occupied Riga in 1202 and in the 1230s they settled in Chełmno Land, a fief of Poland. They first conquered other neighboring Baltic tribes—Curonians, Semigallians, Latgalians, Selonians, and Old Prussians—in the Livonian Crusade and Prussian Crusade.
Benedict Makrai was a well-educated Hungarian noble and diplomat in the service of Sigismund of Luxemburg, King of Hungary and later Holy Roman Emperor. He is best known for his 1412–13 mission to Poland–Lithuania to mediate their territorial dispute with the Teutonic Knights over Samogitia and Masovia in the aftermath of the Battle of Grunwald (1410). His mission did not resolve the dispute and only heightened the tensions.
