Shahi Island (Persian: جزیرهٔ شاهی, Azerbaijani: شاهی آداسؽ|script=Arab|italic=no|, Armenian: Արքայից կղզի), which literally translate to King Island, is the largest island in Urmia Lake, East Azerbaijan Province in Iran. It was renamed to Islami Island after the 1979 Revolution. Located in the eastern part of the lake, Shahi Island has a surface area of 23,000 hectares. The island is the only inhabited island in Lake Urmia, with seven villages, including Burachalu, Ghebchagh, Teymurlu, and Bahramabad. These villages were located on the shores of the island. However the water level in the lake has been falling, and the "island" is now connected to the mainland on its eastern side and it forms a peninsula.
The Shahi island is a rural district (dehestan) in Osku County.
In 1265 Hulagu Khan, the Mongol conqueror of Bagdad, was buried in a mountain (or castle[1]) in the island supposedly with all of his wealth.[2] His tomb has still not been uncovered.[3]
After Iranian revolution on 1979 and overthrow of Iranian monarchy, the revolutionaries changed the name of the island to Islami Island (Jazireh-ye-Eslami), which means Islamic Island.
