Flag of Bahrain

This rectangular flag features a white vertical band on the hoist side and a larger red field on the fly. A serrated edge composed of five white triangles serves as the boundary between the two color sections. The design maintains a 3:5 aspect ratio and contains no additional symbols or emblems.

Red signifies the traditional color of the Al Khalifa dynasty and other historical groups in the Persian Gulf region. The white portion represents peace, a historical designation originating from maritime agreements aimed at ending regional conflict. Each of the five serrated triangles specifically denotes one of the Five Pillars of Islam, anchoring the national identity in religious tradition. These elements combine to honor both the country's ancient heritage and its contemporary Islamic values.

A white vertical stripe was first added to the traditionally red banner in 1820 to signify a truce under the General Maritime Treaty with Great Britain. Following the introduction of the serrated edge in 1932, the government officially adopted a version with eight points in 1972. In 2002, the number of points was formally reduced to five to coincide with the nation's transition to a constitutional monarchy. This evolution reflects the standardization of the flag's proportions and its symbolic elements over nearly two centuries.
