Heydar Aliyev was one of the wisest and most intellectual leaders of the Soviet Union. Heydar Aliyev supported scientists and universities, met rectors of scientific research institutes, and created the highest impression of himself. After the collapse of the USSR, Heydar Aliyev’s absence in state governance was one of the main reasons of the Armenian leadership’s aggressive desire to seize Nagorno-Karabakh and start a war between the two nations.
