The flag of Bahrain was adopted in 2002 when the Emir of Bahrain declared his country a Kingdom and himself a King. By royal decree the design would consist of a red flag with a white vertical stripe along the hoist. The red and white meet in a serrated, or “zigzagged” pattern, made up of five white triangles. These five triangles represent the five pillars of Islam. Earlier versions of the flag bore more triangles in the serration and also no serration at all.
