Muhu

Together with the neighbouring islets of Kesselaid, Viirelaid, Võilaid and Suurlaid, Muhu forms Muhu Parish, a rural municipality in Saare County. The German names for the island are Mohn and Moon. Moon is also the Swedish name for the island. The main settlements are Kuivastu (ferry harbour), Liiva (administrative centre) and Koguva (traditional village ensemble and the Muhu Museum).

The island is divided from mainland Estonia by the Big Strait (Estonian: Suur väin) and from Saaremaa by the Little Strait (Estonian: Väike väin). The Sea of Straits (Estonian: Väinameri, German: Moonsund, Moon Sound) lies north of the island. The island also has the Üügu Nature Reserve.

In January 1227, an army of the Livonian Brothers of the Sword with Letts, Germans of Riga and native Livonians (20,000 men commanded by William of Modena) crossed on sea ice from the mainland and attacked the island of Saaremaa to reduce the last holdout of pagan Estonians. The Estonians surrendered on Muhu at a circular stronghold called Mona, the earthworks of which are still preserved near the causeway between the islands. This ended the Estonian Crusade.

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 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.

The same waters also saw the Battle of Moon Sound during World War I in September-October 1917 between Russian and German naval forces.
