The Republic of Azerbaijan, also called simply as Azerbaijan is a country situated in between Eastern Europe and Western Asia. It has the Caspian Sea to the east and shares its borders with Russia, Georgia, Armenia and Iran. Baku is the capital of Azerbaijan and is the only metropolis in the country. The country was initially known as the Azerbaijan Democratic Republic and first got its independence in the year 1918 and was eventually incorporated in the USSR in 1920. It then came to be known as the Azerbaijan Soviet Socialist Republic. However, when the USSR dissolved in 1991, the country became an independent one. Also, it became the first secular democratic Muslim-majority state. Azerbaijan is also a unitary state where the Central Government is considered as a supreme power. Also, the country is also a semi-presidential republic. It also shares diplomatic relations with over 158 countries and is a member of 38 international organisations like the United Nations, the Council of Europe and the NATO Partnership for Peace (PfP) program. The country also holds an observer position in the World Trade Organisation (WTO). Almost the entire population belongs to the Islam religion. Another interesting fact is that the country’s constitution does not have one religion as its official religion; all the political forces consider themselves a secularist.
