Gedvydas (or Edivid) (believed to have died ca. 1253) was one of the sons of Dausprungas and nephews of King of Lithuania Mindaugas. Gedvydas together with his brother Tautvilas and uncle Vykintas waged a civil war against Mindaugas. Gedvydas' brother and uncle were more active and Gedvydas played just a secondary role in the conflict. The war resulted in coronation of Mindaugas.
In 1248, Mindaugas sent Tautvilas, Gedvydas, and Vykintas to conquer Smolensk promising that they could keep what they would conquer. On the Protva River they defeated Duke of Moscow but near Zubtsov lost to the Duke of Vladimir-Suzdal. After discovering about the failure, Mindaugas took their land and property for himself. At the beginning of 1249, Tautvilas, Gedvydas, and Vykintas fled to Daniel of Halych, who was married to Gedvydas' sister. They formed a powerful coalition with the Samogitians, the Livonian Order, and Vasilko of Volhynia in opposition to Mindaugas. An internal war erupted. Daniel and the Livonian Order organized several military campaigns into Mindaugas lands.
The Livonian Order became an ally of Mindaugas after he agreed to baptize. In 1251, the remaining allies attacked Mindaugas in Voruta, but the attack failed. Tautvilas' and Gedvydas' forces retreated to defend themselves in Vykintas castle in the present-day Rietavas municipality. Neither side seems to have won. Vykintas died in or about 1253, and Gedvydas was forced to flee to Halych. There he helped Daniel in an unsuccessful campaign against Bohemia. This is the last mention of Gedvydas in written sources, and historians assume he perished in the battle.
The Northern Crusades or Baltic Crusades were Christian colonization and Christianization campaigns undertaken by Catholic Christian military orders and kingdoms, primarily against the pagan Baltic, Finnic and West Slavic peoples around the southern and eastern shores of the Baltic Sea, and to a lesser extent also against Orthodox Christian Slavs.
Morta was Queen Consort of Lithuania (1253–1262) upon the accession of her husband, King Mindaugas. Very little is known about her life. Probably, Morta was Mindaugas' second wife as Vaišvilkas, the eldest son of Mindaugas, was already a mature man active in international politics when Morta's sons were still young and dependent on the parents. After her death, Mindaugas married her sister, the wife of Daumantas. In revenge, Daumantas allied with Treniota and assassinated Mindaugas and two of Morta's sons in 1263.
The Grand Duchy of Lithuania was a European state that existed from the 13th century to 1795, when the territory was partitioned among the Russian Empire, the Kingdom of Prussia, and the Habsburg Empire of Austria. The state was founded by Lithuanians, who were at the time a polytheistic nation born from several united Baltic tribes from Aukštaitija.
The Battle of Saule was fought on 22 September 1236, between the Livonian Brothers of the Sword and pagan troops of Samogitians and Semigallians. Between 48 and 60 knights were killed, including the Livonian Master, Volkwin. It was the earliest large-scale defeat suffered by the orders in Baltic lands. The Sword-Brothers, the first Catholic military order established in the Baltic lands, was soundly defeated and its remnants accepted incorporation into the Teutonic Order in 1237. The battle inspired rebellions among the Curonians, Semigallians, Selonians, Oeselians, tribes previously conquered by the Sword-Brothers. Some thirty years' worth of conquests on the left bank of Daugava were lost. To commemorate the battle, in 2000 the Lithuanian and Latvian parliaments declared 22 September to be the Baltic Unity Day.
Traidenis was the Grand Duke of Lithuania from 1270 until 1282. He is the second most prominent, after Mindaugas, Grand Duke of Lithuania in the 13th century. His reign ended a seven-year unrest period after Mindaugas was assassinated in 1263 and firmly established the Grand Duchy as a pagan state for another hundred years.
Vaišvilkas or Vaišelga was the Grand Duke of Lithuania (1264–1267). He was son of Mindaugas, the first and only Christian King of Lithuania.
Dausprungas was the older brother of Mindaugas, the first King of Lithuania. Dausprungas is mentioned in the peace treaty with Galicia–Volhynia in 1219 among the 21 early dukes of Lithuania as one of the five elder dukes, the other four being Živinbudas, Daujotas, Mindaugas and Viligaila. Since Dausprungas is the only known brother of Mindaugas, Mindaugas' nephews Edivydas and Tautvilas are presumed to be his sons. If that is true, then Dausprungas is father-in-law of Daniel of Halych and he was also married to Vykintas' sister. Because it is known that Mindaugas used to kill his relatives to gain power and because Dausprungas is not mentioned in any other sources, some imply that he was killed by Mindaugas, but others rebut since his sons still ruled their lands in 1248.
The Kingdom of Lithuania was a Lithuanian state, which existed roughly from 1251 to 1263. King Mindaugas was the first and only Lithuanian monarch crowned King of Lithuania with the assent of the Pope. The formation of the Kingdom of Lithuania was a partially successful attempt at unifying all surrounding Baltic tribes, including the Old Prussians, into a single state.
Vykintas was Duke of Samogitia and a rival to the future King of Lithuania, Mindaugas. In 1236 he probably led the Samogitian forces in the Battle of Saule against the Livonian Order. The Order suffered a great defeat and was near the brink of collapse, forcing it to become a branch of the Teutonic Knights.
The Battle of Skuodas or Schoden was a medieval battle fought in ca. 1259 near Skuodas in present-day Lithuania during the Lithuanian Crusade. The Samogitian army of 3,000 invaded Courland and on their way back defeated the Livonian Order, killing 33 knights and many more low-rank soldiers. In terms of knights killed, it was the eighth largest defeat of the Livonian Order in the 13th century. This victory led to a Semigallian insurrection against the Livonian crusaders, which lasted from 1259 to 1272.
The Battle of Durbe was a medieval battle fought near Durbe, 23 km (14 mi) east of Liepāja, in present-day Latvia during the Livonian Crusade. On 13 July 1260, the Samogitians soundly defeated the joint forces of the Teutonic Knights from Prussia and Livonian Order from Livonia. Some 150 knights were killed, including Livonian Master Burchard von Hornhausen and Prussian Land Marshal Henrik Botel. It was by far the largest defeat of the knights in the 13th century: in the second-largest, the Battle of Aizkraukle, 71 knights were killed. The battle inspired the Great Prussian Uprising and the rebellions of the Semigallians, the Couronians, and the Oeselians. The battle undid two decades of Livonian conquests and it took some thirty years for the Livonian Order to restore its control.
Daumantas or Dovmont, was a Lithuanian prince best remembered as a military leader of the Principality of Pskov between 1266 and 1299. During his term in office, Pskov became de facto independent from Novgorod.
The House of Mindaugas was the first royal family of Grand Duchy of Lithuania, centered on Mindaugas, the first known and undoubted sovereign of Lithuania. He was crowned as King of Lithuania in 1253 and assassinated ten years later. His known family relations end with children; there is no data on his great-grandchildren or any relations with the Gediminids, a dynasty of sovereigns of Lithuania and Poland that started with Butigeidis ca. 1285 and ended with Sigismund II Augustus in 1572.
Boroldai, also known as Burundai, was a notable Mongol general of the mid 13th century. He participated in the Mongol invasion of Russia and Europe in 1236-1242.
Siemowit I of Masovia, was a Polish prince member of the House of Piast, Duke of Czersk during 1247-1248, Duke of Masovia during 1248-1262, ruler over Sieradz during 1259-1260.
The Christianization of Lithuania occurred in 1387, initiated by King of Poland and Grand Duke of Lithuania Władysław II Jagiełło and his cousin Vytautas the Great. It signified the official adoption of Christianity by Lithuania, the last pagan country in Europe. This event ended one of the most complicated and lengthiest processes of Christianization in European history.
Mindaugas is the first known Grand Duke of Lithuania and the only crowned King of Lithuania. Little is known of his origins, early life, or rise to power; he is mentioned in a 1219 treaty as an elder duke, and in 1236 as the leader of all the Lithuanians. The contemporary and modern sources discussing his ascent mention strategic marriages along with banishment or murder of his rivals. He extended his domain into regions southeast of Lithuania proper during the 1230s and 1240s. In 1250 or 1251, during the course of internal power struggles, he was baptised as a Roman Catholic; this action enabled him to establish an alliance with the Livonian Order, a long-standing antagonist of the Lithuanians. During the summer of 1253 he was crowned King of Lithuania, ruling between 300,000 and 400,000 subjects.
The history of Lithuania between 1219 and 1295 concerns the establishment and early history of the first Lithuanian state, the Grand Duchy of Lithuania. The beginning of the 13th century marks the end of the prehistory of Lithuania. From this point on the history of Lithuania is recorded in chronicles, treaties, and other written documents. In 1219, 21 Lithuanian dukes signed a peace treaty with Galicia–Volhynia. This event is widely accepted as the first proof that the Baltic tribes were uniting and consolidating. Despite continuous warfare with two Christian orders, the Livonian Order and the Teutonic Knights, the Grand Duchy of Lithuania was established and gained some control over the lands of Black Ruthenia, Polatsk, Minsk, and other territories east of modern-day Lithuania that had become weak and vulnerable after the collapse of Kievan Rus'.
Tautvilas was Duke of Polotsk and one of Dausprungas' sons and nephews of King of Lithuania Mindaugas. Tautvilas together with his brother Gedvydas and uncle Vykintas waged a civil war against Mindaugas. The war resulted in Mindaugas' coronation.
