Armenia is a landlocked mountainous country in the Caucasus region of Eurasia. Situated at the juncture of Western Asia and Eastern Europe, it is bordered by Turkey to the west, Georgia to the north, Azerbaijan to the east, and Iran and Nakhchivan to the south.
A former republic of the Soviet Union, Armenia is a unitary, multiparty, democratic nation-state with an ancient and historic cultural heritage. The Kingdom of Armenia was the first state to adopt Christianity as its religion in the early years of the 4th century (the traditional date is 301). The modern Republic of Armenia recognizes the exclusive historical mission of the Armenian Apostolic Church as a national church, although the modern Republic of Armenia has separation of church and state.
