Azerbaijan lies on the boundary between Western Asia and Eastern Europe, in the South Caucasus, with the Caspian Sea along its entire eastern edge and Iran to the south. Baku is both the capital and the largest city.
The country is not one continuous block. The exclave of Nakhchivan is cut off from the rest by Armenian territory, and it holds the only stretch of border Azerbaijan shares with Turkey. Georgia is the neighbour to the northwest and Russia's republic of Dagestan to the north. It is one of six independent Turkic states, and the first secular democratic Muslim-majority state in the world, declared in 1918.
