A sheikhdom (alt. sheikdom) (Arabic: مشيخة [Mashyakhah]) is a geographical area or a society ruled by a tribal leader called sheikh (Arabic: شيخ). Sheikhdoms exist almost exclusively within Arab countries, particularly in the Arabian Peninsula.
The word is generally used as a descriptive term for political systems rather than as a noun (such as the case is with "Kingdom"), and although some countries are ruled by a sheikh, they are not typically referred to as sheikdoms, but kingdom, emirate, or simply state, and their ruler usually has another royal title such as king or emir.
