Kamil Aliyev was born on October 22, 1921, in Yerevan, Armenian Soviet Socialist Republic (present-day Yerevan, Armenia). He was a son of Museyib Aliyev. During the period of bloody massacres, carried out mercilessly by Armenians against Azerbaijanis, the Aliyevs were forced to flee from their homeland. As a result, the family settled down in Turkey in 1922. Shortly afterwards, the family returned to Yerevan, however, they soon had to move to Baku because of the continuing ruthlessness of the Armenians. In 1934, Kamil's father died and his mother had to bring up her five children alone.
