Hiiumaa in the context of "Saaremaa"

Estonia, officially the Republic of Estonia, is a country in Northern Europe. It is bordered to the north by the Gulf of Finland across from Finland, to the west by the Baltic Sea across from Sweden, to the south by Latvia, and to the east by Russia. The territory of Estonia consists of the mainland, the larger islands of Saaremaa and Hiiumaa, and over 2,300 other islands and islets on the east coast of the Baltic Sea. Its capital Tallinn and Tartu are the two largest urban areas. The Estonian language, of the Finnic family, is the official language and the first language of the majority of its population of nearly 1.4 million. Estonia is one of the least populous members of the European Union and NATO.

Present-day Estonia has been inhabited since at least 9,000 BC. The medieval indigenous population of Estonia was one of the last pagan civilisations in Europe to adopt Christianity following the Northern Crusades in the 13th century. After centuries of successive rule by the Teutonic Order, Denmark, Sweden, and the Russian Empire, a distinct Estonian national identity began to emerge in the mid-19th century. This culminated in the 1918 Estonian Declaration of Independence from the then-warring Russian and German empires. Democratic throughout most of the interwar period, Estonia declared neutrality at the outbreak of World War II, but the country was repeatedly invaded and occupied, and ultimately annexed into the USSR. Throughout the de facto Soviet occupation, from World War II until 1991, Estonia's de jure state continuity was preserved by diplomatic representatives and the government-in-exile. Following the 1988–90 "Singing Revolution" against Soviet rule, full independence was restored on 20 August 1991.

Estonia under Swedish rule signifies the period of time between 1561 and 1710, when present-day Estonia was under the rule of the Swedish Empire. In the wake of the breakup of the State of the Teutonic Order, the Baltic German local nobility in the areas of Harrien (Harjumaa) and Wierland (Virumaa), as well as the city of Reval (Tallinn) in June 1561 (and somewhat later Jerwen (Järvamaa)) asked for and were granted protection by the Swedish king Eric XIV, leading to Swedish involvement in the Livonian War. At the conclusion of hostilities in 1583, Sweden was in control of the northern parts of modern Estonia and Dagö (Hiiumaa island); the Duchy of Estonia was created from this territory. Following renewed wars between Poland and Sweden, the southern parts of present-day Estonia (then Livonia) were incorporated into Sweden by the Treaty of Altmark in 1629. Sweden also conquered the island of Ösel (Saaremaa) from Denmark, and were thus in control of all of present-day Estonia.

The time of Swedish rule came to an effective end in 1710, when all the Swedish Baltic provinces capitulated to Russian troops during the end-stages of the Great Northern War. Russian hegemony was formalized in 1721.

The West Estonian archipelago (Estonian: Lääne-Eesti saarestik, also Moonsund archipelago) is a group of Estonian islands located in the Baltic Sea around Väinameri. The total area is about 4,000 km (1,500 sq mi). The archipelago is composed of the islands Saaremaa, Hiiumaa, Muhu, Vormsi and about 900 other smaller islands. The archipelago is separated from the Estonian mainland by the Väinameri Sea.

Kärdla (Estonian pronunciation: [ˈkærˑ'dlɑ]; Swedish: Kärrdal; German: Kertel) is the only town on the island of Hiiumaa, Estonia. It is the capital of Hiiu County and the administrative center of Hiiumaa Parish. The Chairman of the District Council of Kärdla is Tõnis Paljasma.

Hiiu County (Estonian: Hiiu maakond or Hiiumaa) is one of 15 counties of Estonia, being the smallest county both in terms of area and population. It consists of Hiiumaa (German and Swedish: Dagö), the second-largest island of Estonia, and several smaller islands near it. The county borders Lääne County to the east and Saare County to the south.

Present-day Estonia has been inhabited since at least 9,000 BC. The medieval indigenous population of Estonia was one of the last pagan civilisations in Europe to adopt Christianity following the Northern Crusades in the 13th century. After centuries of foreign rule by the Teutonic Order, Denmark, Poland, Sweden, and the Russian Empire, a distinct Estonian national identity gained new momentum with the Age of Awakening in the mid-19th century. This culminated in the 1918 Estonian Declaration of Independence. Democratic throughout most of the interwar period, Estonia declared neutrality at the outbreak of World War II, but the country was repeatedly invaded and occupied, and ultimately annexed into the USSR.

Estonia is a unitary country with a single-tier local government system. Local affairs are managed autonomously by local governments.

Since administrative reform in 2017, there are in total 79 local governments, including 15 towns and 64 rural municipalities. All municipalities have equal legal status and form part of a county, which is a state administrative unit. Representative body of local authorities is municipal council, elected at general direct elections for a four-year term. The council appoints local government, headed by a mayor. For additional decentralization the local authorities may form municipal districts with limited authority, currently those have been formed in Tallinn and Hiiumaa.
