3x5 Kingdom of Bahrain Flag

The original flag of Bahrain was a red field. In 1820 Bahrain signed a treaty with the United Kingdom and added a white stripe to the original red flag to indicate the truce, and in 1932 a serrated edge was added to distinguish the flag of Bahrain from those of its neighbors. The flag originally had twenty-eight white points, but this was reduced to eight in 1972 and to five in 2002 so that each of the points could stand for one of the Five Pillars of Islam.
