Livonia, known in earlier records as Livland, is a historical region on the eastern shores of the Baltic Sea. It is named after the Livonians, who lived on the shores of present-day Latvia.
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.
Alexander Yaroslavich Nevsky was Prince of Novgorod, Grand Prince of Kiev (1246–1263) and Grand Prince of Vladimir (1252–1263).
The Livonian Chronicle of Henry is a Latin narrative of events in Livonia and surrounding areas from 1180 to 1227. It was written c. 1229 by a priest named Henry. Apart from some references in Gesta Danorum – a patriotic work by the 12th-century Danish historian Saxo Grammaticus – and few mentions in the Primary Chronicle compiled in Kievan Rus', the Chronicle of Henry is the oldest known written document about the history of Estonia and Latvia.
The Novgorod Republic was a medieval state that existed from the 12th to 15th centuries in northern Russia, stretching from the Gulf of Finland in the west to the northern Ural Mountains in the east. Its capital was the city of Novgorod. The republic prospered as the easternmost trading post of the Hanseatic League, and its people were much influenced by the culture of the Byzantines, with the Novgorod school of icon painting producing many fine works.
The Battle of the Neva was fought between the Novgorod Republic, along with Karelians, and the Kingdom of Sweden, including Norwegian, Finnish and Tavastian forces, on the Neva River, near the settlement of Ust-Izhora, on 15 July 1240. The battle is mentioned only in Russian sources, and it remains unclear whether it was a major invasion or a small-scale raid. In Russian historiography, it has become an event of massive scale and importance.
Koporye is a historic village (selo) in Leningrad Oblast, Russia, located about 100 km (62 mi) west of St. Petersburg and 12 km (7.5 mi) south of the Koporye Bay of the Baltic Sea. Its population in 2017 was 1,603.
The Battle on the Ice, also known as the Battle of Lake Peipus or Battle of Lake Chud, took place on 5 April 1242. It was fought on or near the frozen Lake Peipus when the united forces of the Republic of Novgorod and Vladimir-Suzdal, led by Prince Alexander Nevsky, emerged victorious against the forces of the Livonian Order and Bishopric of Dorpat, led by Bishop Hermann of Dorpat.
Ugandi was an independent county between the east coast of Lake Võrtsjärv and west coast of Lake Pskov, bordered by Vaiga, Mõhu, Nurmekund, Sakala, Tālava, and The Principality of Pskov. Ugandi had an area of approximately 3000 hides. Ugandi corresponded roughly to the present Estonia's territory of Võru County, Põlva County and half of Tartu County and Valga County, as well as Petseri County.
Vyachko, also known as Vetseke, was the prince of Koknese (Kuikenos). He later became the prince of Yuryev while in the service of Novgorod, which was the last Russian stronghold in Estonia. He died during the defense of the city against the Livonian Brothers of the Sword in 1224.
The Swedish–Novgorodian Wars were a series of armed conflicts during the 12th and 13th centuries, fought between the Novgorod Republic and medieval Sweden over control of the Gulf of Finland. Part of the trade route from the Varangians to the Greeks, the area was vital to the Hanseatic League. The clashes between Catholic Swedes and Orthodox Novgorodians had religious overtones, but before the 14th century there is no knowledge of official crusade bulls issued by the pope.
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 Battle of Wesenberg, Rakvere or Rakovor was fought on 18 February 1268 between the combined forces of Danish Estonia, the Bishopric of Dorpat, the Livonian Order, and local Estonian militias on one side, and the forces of Novgorod and Pskov, led by Dmitry of Pereslavl, on the other. Medieval accounts of the battle vary with both sides claiming victory; however, the Livonian victory is seen as more plausible as Novgorodian-Pskovian forces retreated out of Danish Estonia, with Livonian Knights launching a retaliatory attack on Izborsk and Pskov soon afterward, in June 1269.
Otto von Lutterberg was the Landmeister of the Livonian Order of the Teutonic Knights from 1267 to 1270.
The Pskov Land was a historical region in the north-west of medieval Russia centred around the city of Pskov. It was a vassal state of various Rus' states and had a measure of independence as Pskov Republic before being annexed by the Grand Duchy of Moscow. It had an important role in the trade and conflicts between Russia and its western neighbours.
Novgorodian Land was one of the largest historical territorial–state formations in Russia, covering its northwest and north. Novgorod Land, centered in Veliky Novgorod, was in the cradle of Kievan Rus' under the rule of the Rurikid dynasty and one of the most important princely thrones of the era. During the collapse of Kievan Rus' and in subsequent centuries, Novgorod Land developed as the Novgorod Republic: an autonomous state with republican forms of government under the suzerainty of the great princes of Vladimir-Suzdal. During the period of greatest development, it reached north to the White Sea, and in the east it has been claimed that it did spread beyond the Ural Mountains. It had extensive trade relations within the framework of the Hanseatic League and with the rest of Rus'. The Principality of Moscow conquered the Novgorod Republic in 1478, and annexed it in 1578, although Novgorod Land continued to exist as an administrative unit until 1708.
The economy of the Pskov Republic (1348–1510) was dominated by merchants trading to and from the city of Pskov and the associated Pskov Land, primarily via the river Velikaya and connected waterways. It also had well-developed farming, fishing, blacksmithing, jewellery-making and construction industries.
The Treaty of Stensby was an agreement between king Valdemar II of Denmark and the Teutonic Order, signed on 7 June 1238 in Stensby on the island of Zealand in Denmark, and confirmed by Innocent IV in September 1243. The arrangement transferred northern maritime Estonia to the Kingdom of Denmark in exchange for military support.
The Danish campaigns to Novgorod were a series of Crusader raids in 1241 by Danish royals and vassals, using the Duchy of Estonia as base of operation, against the Novgorod Republic. The Danish Crusades were supported and executed in coordination with the papacy and other Crusading states, notably Sweden and the Livonian Order, the former one not being able to send further support after being defeated at the Neva.
