Sheikh Celal (Bozoklu Celal)
Sheikh Celal, called Bozoklu from his native Bozok, later Yozgat, was an Ottoman Alevi preacher in Anatolia who gave his name to the Celali rebellions. In 1519, under Selim I, he led a revolt of hard-pressed peasants and dispossessed soldiery around Tokat.
He drew support from Turkmen stirred by Safavid agitation. The rising, the first Celali rebellion, was bloodily suppressed within the year, and later writers gave Celal's name to the Anatolian rebel movements that followed.
