The House of Giray (Crimean Tatar: Geraylar, كرايلر; Ottoman Turkish: آل جنكيز, romanized: Âl-i Cengiz, lit. 'Genghisids'), also the Girays, were a Genghisid Turkic dynasty that reigned in the Khanate of Crimea from its formation in 1431 until its downfall in 1783. The dynasty also supplied several khans of Kazan and Astrakhan between 1521 and 1550. Apart from the royal Girays, there was also a lateral branch, the Choban Girays (Çoban Geraylar).
Before reaching the age of majority, young Girays were brought up in one of the Circassian tribes, where they were instructed in the arts of war. The Giray Khans were elected by other Crimean Tatar dynasts, called myrzas (mırzalar). They also elected an heir apparent, called the qalgha sultan (qalğa sultan). In later centuries, the Ottoman Sultan obtained the right of installing and deposing the khans at his will.
