ایلخانی (Ilkhanate) was a Mongol state that ruled over Persia and parts of the Middle East from the 13th to the 14th centuries. Established by Hulagu Khan, a grandson of Genghis Khan, it became a significant part of the larger Mongol Empire. The Ilkhanate is known for its cultural and economic achievements, including the promotion of trade and the arts. The Ilkhanate played a crucial role in the spread of Islam in the region, as many of its rulers converted to the religion. This led to a blending of Mongol and Persian cultures, influencing architecture, literature, and governance. The state eventually declined due to internal strife and external pressures, leading to its dissolution in the 1330s.
