The Bahranian flag consists of a red base with a white vertical stripe on the left side that has a serration or a zigzag made of five white triangles. The triangles point to the right side of the flag.

Meaning:
The triangles on the white serrated stripe represent the five pillars of Islam. The color red is supposed to represent the Kharijite sect of Islam. Bahrain's older flags used to be entirely red, but a white stripe was added in the 19th Century to indicate truces Bahrain had made with neighboring countries. The serrated triangles were added to the white strips to distinguish the Bahranian flag from the flags of its neighboring countries.

History:
The present day Bahranian flag was adopted on Feb. 14, 2002 after the Emir of Bahrain declared his country a Kingdom and himself a King. The British had withdrawn from Bahrain in 1971 making it an independent emirate.
