Bohemia

The Czech state, known as Bohemia and later as the Bohemian Crown, was formed in the late 9th century. The country reached its greatest territorial extent during the 13th and 14th century, under the rule of the Přemysli and Luxembourg dynasties. Following the dissolution of Czechoslovakia at the end of 1992, the Czech part of the former nation found itself without a common single-word name in English. In 1993, the Czech Ministry of Foreign Affairs suggested the name Czechia /ˈtʃɛki.ə/ (Česko [ˈtʃɛskɔ] in Czech) as an official alternative in all situations other than formal official documents and the full names of government institutions; however, this has not become widespread in English, even though most other languages have single-word names for the country (usually their own variants of "Czechia"). http://en.wikipedia.org/wiki/Czech_Republic#Bohemia
