The Yazidi heritage of the Kurdish Mahmudi dynasty

The architecture of the Kurdish Mahmudi dynasty appears to have a history that extends beyond a tribute to the dynasty's Yezidi heritage. The mausoleums of two monarchs include distinct Yezidi characteristics, indicating that Yezidi rituals were preserved at their final resting place. The preservation of central Yezidi rituals at these converted monarchs' resting places under Ottoman coercion can be understood in a variety of ways. The data's most basic explanation is that rulers' political transformations and the formation of a new outer shell had little direct impact on the average Mahmudi tribesman. Widespread conversion was a lengthy process, comparable to the scenario with other Kurdish dynasties that altered symbolism/political rhetoric in response to political pressures during the Ottoman-Safavid period.
