Saare County is one of 15 counties of Estonia. It consists of Saaremaa, the largest island of Estonia, and several smaller islands near it, most notably Muhu, Ruhnu, Abruka and Vilsandi. The county borders Lääne County to the east, Hiiu County to the north, and Latvia to the south. In January 2013 Saare County had a population of 30,966, which was 2.4% of the population of Estonia.
The Battle of Inab, also called Battle of Ard al-Hâtim or Fons Muratus, was fought on 29 June 1149, during the Second Crusade. The Zengid army of Atabeg Nur ad-Din Zangi destroyed the combined army of Prince Raymond of Poitiers and the Assassins of Ali ibn-Wafa. The Principality of Antioch was subsequently pillaged and reduced in size as its eastern border was pushed west.
Muhu, is an island in the West Estonian archipelago of the Baltic Sea. With an area of 198 km2 (76 sq mi) it is the third largest island belonging to Estonia, after Saaremaa and Hiiumaa.
Ugaunians or Ugannians, referred to as Chudes by the earliest Russian chronicles were historical Finnic people inhabiting the ancient southern Estonian Ugandi County (Latin:Ungannia) that is now Tartu, Põlva, Võru and Valga counties of Estonia.
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.
Saint George's Night Uprising in 1343–1345 was an unsuccessful attempt by the indigenous Estonian population in the Duchy of Estonia, the Bishopric of Ösel-Wiek, and the insular territories of the State of the Teutonic Order to rid themselves of Danish and German rulers and landlords who had conquered the country in the 13th century during the Livonian Crusade; and to eradicate the non-indigenous Christian religion. After initial success the revolt was ended by the invasion of the Teutonic Order. In 1346, the Duchy of Estonia was sold for 19,000 Köln marks by the King of Denmark to the Teutonic Order. The shift of sovereignty from Denmark to the State of the Teutonic Order took place on November 1, 1346.
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.
The Battle of Lihula or Battle of Leal was fought between invading Swedes and Estonians for the control of a castle in Lihula, Estonia in 1220.

Oeselians is a term historically applied before the Northern Crusades up to the 13th century to people who were living on the island of Saaremaa or Oesel as it was known back then, an island in Estonia in the Baltic Sea. In modern times they are sometimes also referred to as Saarlased. In Viking-Age literature, the inhabitants were often included under the name "Vikings from Estonia". The name Oeselians was first used in writing by Henry of Livonia in the 13th century. The inhabitants are often mentioned in the historic written sources during the Estonian Viking Age.
The Livonian crusade refers to the various military Christianisation campaigns in medieval Livonia – in what is now Latvia and Estonia – during the Papal-sanctioned Northern Crusades in the 12–13th 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 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.

Victory over the Swedish army in the Battle of Lihula inspired the Oeselians to further fighting. In 1221 they tried to conquer the Danish stronghold in Tallinn with the help of Revalians, Harrians, and Vironians. They besieged the stronghold for 14 days and all Danish outbreaks were repulsed. One day, four cogs appeared unexpectedly, which the Oeselians thought to have been carrying the Royal Army of the Danish king. The siege was ended and the Oeselians left.
The Valjala Stronghold was a major ringfort on the island of Saaremaa in Estonia. Established in the 12th century, at the time it was the most important Oeselian stronghold. Its surrender in 1227 finalized the crusader conquest of Estonia.
