Armenia

parliamentary democracy; note - constitutional changes adopted in December 2015 transformed the government to a parliamentary system

Armenia prides itself on being the first state to formally adopt Christianity (early 4th century). Armenia has existed as a political entity for centuries, but for much of its history it was under the sway of various empires, including the Roman, Byzantine, Arab, Persian, Ottoman, and Russian. During World War I, the Ottoman Empire instituted a policy of forced resettlement that, coupled with other harsh practices targeting its Armenian subjects, resulted in at least 1 million deaths; these actions have been widely recognized as constituting genocide.
