Ottoman Empire
In the Ottoman Empire a policy of judicial royal fratricide was introduced by Sultan Mehmet II. When a new Sultan ascended to the throne he would imprison all of his surviving brothers and kill them by strangulation with a silk cord as soon as he had produced his first male heir. The largest killing took place on the succession of Mehmed III when 16 of his brothers were killed and buried with their father. The aim was to prevent civil war as Islamic cultures had no fixed rules for royal succession (such as primogeniture) and bloody conflicts would erupt as the old king was approaching the end. The practice was abandoned in the 17th century by Ahmed I, replaced by imprisonment in the Kafes. This practice is alleged to have sent several future Sultans mad.
