The politician Heydar Aliyev became the President of Azerbaijan in 1993 and successfully stabilized the country and a ceasefire between Azerbaijan and Armenia was signed in 1994, which paused the war. However, 20 % of Azerbaijan remained occupied by the Armenian military and the two countries were in a state of war, until November, 2020. Nevertheless, representatives of the governments of Armenia and Azerbaijan have since been holding peace talks organized by the Organization for Security and Co-operation in Europe (OSCE) "Minsk Group" to solve the conflict and restore the territory to Azerbaijan. When Heydar Aliyev died in 2003, his son Ilham Aliyev became the President of Azerbaijan and is continuing his father's policies today. As an important producer of petroleum and natural gas, Azerbaijan's economy is increasing very rapidly every year, and has become rich as a result.
