[1] After his father's death, for twelve years (1466–1478), the throne alternated between Hayder's brothers Nur Devlet and Meñli I Giray.
During one of Mengli's reigns Hayder was held in honorable confinement at the Genoese fortress of Sudak.
They released Nur Devlet from prison in Sudak and made him khan.
Nur Devlet proved unpopular and in the spring of 1478 the Turks released their prisoner Mengli and placed him on the throne.
Hayder and Nur Devlet fled to Kiev in the Polish Kingdom.
