Tautvilas (or Tautvila; died 1263) was Lithuanian 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.
In 1248, Mindaugas sent Tautvilas, Edivydas, and Vykintas to conquer Smolensk promising that they could keep what they would conquer. On the Protva River they defeated the Duke of Moscow but 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, Edivydas, and Vykintas fled to Daniel of Galicia, who was married to Tautvilas' sister. They formed a powerful coalition with the Samogitians, the Livonian Order, and Vasilko of Volhynia in opposition to Mindaugas. An internal war erupted. While Daniel and the Livonian Order were organizing military campaigns into Mindaugas lands, Tautvilas travelled to Riga, where he was baptized by the Archbishop in 1250.
Mindaugas thwarted the coalition by agreeing to baptize and relinquish control over some lands in the western Lithuania, for which he was to receive a crown in return. The Livonian Order became an ally. In 1252, Tautvilas and the remaining allies attacked Mindaugas in Voruta, sometimes considered to be the first capital of Lithuania. The attack failed and Tautvilas' forces retreated to defend themselves in Vykintas castle in the present-day Rietavas Municipality. Neither side seems to have won, but Vykintas died in or about 1253, and Tautvilas was forced to flee to Galicia. There he helped Daniel in an unsuccessful campaign against Bohemia. Daniel reconciled with Mindaugas in 1254 and Tautvilas recognized Mindaugas' superiority. In return he received Polotsk as a fiefdom.
While governing Polatsk, his main concern was to secure a trading route from Polatsk along the Daugava to the upper Dnieper River. Tautvilas managed to take away the Principality of Vitebsk from the Dukes of Novogrudok. His son Constantine became the ruler of Vitebsk. After Mindaugas was assassinated by Treniota and Daumantas, Tautvilas wished to assume the title of Grand Duke of Lithuania, but was killed by his cousin Treniota in 1263.
Morta was Queen 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 sovereign state in northeastern Europe that existed from the 13th century, succeeding the Kingdom of Lithuania, to the late 18th century, when the territory was suppressed during the 1795 partitions of Poland–Lithuania. The state was founded by Lithuanians, who were at the time a polytheistic nation of several united Baltic tribes from Aukštaitija, which by 1440, became the largest European state controlling an area from the Baltic Sea in the north to the Black Sea in the south.
Traidenis was Grand Duke of Lithuania from 1269 or 1270 until 1282. He is the second most prominent grand duke of Lithuania in the 13th century after Mindaugas. 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.
Erdvilas was one of the 21 early dukes of Lithuania who signed a treaty with Galicia–Volhynia in 1219. He and Vykintas are the two dukes of Samogitia mentioned in the treaty. This is supported by the fact that the eastern part of Samogitia supported King of Lithuania Mindaugas, while the western part, ruled by Vykintas, was more hostile. That is the only mention of him in written sources. Few historians consider that Treniota, Mindaugas' nephew, was son of Erdvilas. However more prefer Vykintas as Treniota's father.
Vaišvilkas or Vaišelga was Grand Duke of Lithuania from 1264 until his death in 1267. He was a 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 sovereign state that existed from the 17 July 1251 until the death of the first crowned king of Lithuania, Mindaugas, on 12 September 1263. Mindaugas was the only Lithuanian monarch crowned king with the assent of the Pope and the head of the first catholic Lithuanian state. The formation of the kingdom is widely regarded as a partially successful attempt at unifying all surrounding Baltic tribes, including the Old Prussians, into a single unified state under a common king.
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 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 the Livonian Order from Livonia. Some 150 knights were killed, including Livonian master Burkhard von Hornhausen and Prussian land marshal Heinrich 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, Domantas or Dovmont was Prince of Pskov from 1266 to 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.
Gedvydas 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 the coronation of Mindaugas.
The Prince of Polotsk ruled the Principality of Polotsk within the realm of Kievan Rus' or within the Grand Duchy of Lithuania from the mid-9th century to 1307.
Andrei of Polotsk was the eldest son of Algirdas, Grand Duke of Lithuania, and his first wife Maria of Vitebsk. He was the Prince of Pskov and Polotsk (1342–1387). As the eldest son of the Grand Duke, Andrei claimed his right to the throne after his father's death in 1377. Algirdas left Jogaila, his eldest son with his second wife Uliana of Tver, as the rightful heir. Andrei's rivalry with Jogaila, Grand Duke of Lithuania and later King of Poland, eventually led to his demise.
The Lithuanian Civil War of 1381–1384 was the first struggle for power between the cousins Jogaila, Grand Duke of Lithuania and later King of Poland, and Vytautas the Great. It began after Jogaila signed the Treaty of Dovydiškės with the Teutonic Knights which was aimed against his uncle Kęstutis, father of Vytautas. Kęstutis briefly seized power in the Grand Duchy, but was betrayed by adherents of Jogaila primarily from Vilnius. During negotiations for a truce Kęstutis and Vytautas were arrested and transported to the Kreva Castle. Kęstutis died there a week later but Vytautas managed to escape and then sought an alliance with the Teutonic Knights. Subsequently their joint forces raided Lithuanian lands. Eventually the cousins were reconciled as Jogaila needed internal stability in anticipation of negotiations with the Grand Duchy of Moscow and the Kingdom of Poland regarding the possible Christianization of Lithuania. The war did not settle the power struggle; it continued during the next Lithuanian Civil War (1389–1392) which was resolved by the signing of the Ostrów Agreement. After more than ten years of struggle, Vytautas finally became the Grand Duke of Lithuania and ruled the country for thirty-eight years.
The Principality of Vitebsk was a Ruthenian principality centered on the city of Vitebsk in modern Belarus, that existed from its founding in 1101 until it was nominally inherited into the Grand Duchy of Lithuania in 1320. Vitebsk would later fall under the complete authority of Lithuania in 1508.
The Christianization of Lithuania occurred in 1387, initiated by King of Poland and Grand Duke of Lithuania Jogaila and his cousin Vytautas the Great. It signified the official adoption of Catholic 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 was 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. By 1245, Mindaugas was already being referred to as "the highest king" in certain documents. During the summer of 1253, he was crowned king, ruling between 300,000 and 400,000 subjects and got nicknamed as Mindaugas the Sapient by the Livonians.
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'.
