The Northern Crusades or Baltic Crusades were 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 also against Orthodox Christian East Slavs.
Samogitia or Žemaitija is one of the five cultural regions of Lithuania and formerly one of the two core administrative divisions of the Grand Duchy of Lithuania alongside Lithuania proper. Žemaitija is located in northwestern Lithuania. Its largest city is Telšiai, while Šiauliai, where Aukštaitian dialect is being spoken, is sometimes also included into Samogitia. Samogitia has a long and distinct cultural history, reflected in the existence of the Samogitian language.
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.
The Battle of Aizkraukle or Ascheraden was fought on 5 March 1279 between the Grand Duchy of Lithuania, led by Traidenis, and the Livonian branch of the Teutonic Order near Aizkraukle in present-day Latvia. The order suffered a great defeat: 71 knights, including the grand master, Ernst von Rassburg, and Eilart Hoberg, leader of the knights from Danish Estonia, were killed. It was the second-largest defeat of the order in the 13th century. After the battle Duke Nameisis of the Semigallians recognized Traidenis as his suzerain.
The Duchy of Samogitia was an administrative unit of the Grand Duchy of Lithuania from 1422. Between 1422 and 1441 it was known as the Eldership of Samogitia. Since the 1540s the Grand Duke of Lithuania also held the title of Duke of Samogitia, although the actual ruler of the province, responsible to the Grand Duke, was known as the General Elder of Samogitia who was self-elected by the Samogitian nobility.
Semigallia, also spelt Semigalia, is one of the Historical Latvian Lands located to the south of the Daugava river and to the north of the Saule region of Samogitia. The territory is split between Latvia and Lithuania, previously inhabited by the Semigallian Baltic tribe. They are noted for their long resistance (1219–1290) against the German crusaders and Teutonic Knights during the Northern Crusades. Semigallians had close linguistic and cultural ties with Samogitians.
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.
The Livonian crusade consists of the various military Christianisation campaigns in medieval Livonia – modern Latvia and Estonia – during the Papal-sanctioned Northern Crusades in the 12th–13th century. The Livonian crusade was conducted mostly by the Holy Roman Empire and the Kingdom of Denmark. It ended with the creation of Terra Mariana and the Danish duchy of Estonia. The lands on the eastern shores of the Baltic Sea were one of the last parts of Europe to be Christianised. The available information is largely based on Livonian Chronicle of Henry.
The Battle of Karuse or Battle on the Ice was fought on 16 February 1270 between the Grand Duchy of Lithuania and the Livonian Order on the frozen Baltic Sea between the island of Muhu and the mainland. The Lithuanians achieved a decisive victory. The battle, named after the village of Karuse, was the fifth-largest defeat of the Livonian or Teutonic Orders in the 13th century. Almost all that is known about the battle comes from the Livonian Rhymed Chronicle, which devoted 192 lines to the battle.
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.
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 Curonians or Kurs were a medieval Baltic tribe living on the shores of the Baltic Sea in the 5th–16th centuries, in what are now western parts of Latvia and Lithuania. They eventually merged with other Baltic tribes contributing to the ethnogenesis of present-day Latvians and Lithuanians. Curonians gave their name to the region of Courland (Kurzeme), and they spoke the Curonian language.
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'.
Vytenis was Grand Duke of Lithuania from c. 1295 to c. 1316. He became the first of the Gediminid dynasty to rule for a considerable amount of time. In the early 14th century, his reputation outshone that of Gediminas, who is regarded by modern historians as one of the greatest Lithuanian rulers. The rule of Vytenis was marked by constant warfare in an effort to consolidate the Grand Duchy of Lithuania with the Ruthenians, Masovians, and the Teutonic Order.
The Battle of Medininkai took place on 27 July 1320 between the Teutonic Order and the Samogitian army near Medininkai.
The Battle of Memel was fought between the Samogitians and the Livonian Order in 1257 near Memel.
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.
