Hawar-Khase (today called Yeşildallı) was historically inhabited by Syriac Orthodox Christians. It was located in the Diyarbakır central district (merkez kaza) in the Diyarbakır sanjak in the Diyarbekir vilayet in c. 1900. In 1914, it was inhabited by 50 Syriacs, according to the list presented to the Paris Peace Conference by the Assyro-Chaldean delegation. Amidst the Sayfo, on 3 May 1915, men from Hawar-Khase and other neighbouring villages were rounded up at Chanaqchi by 150 militiamen led by Shakir Bey and members of the Kurdish Rama tribe led by Ömer and taken to a pit near the village of Hawar-Dejla, where they were shot. 164 men were murdered in total.
