The national flag of Bosnia and Herzegovina contains a medium blue field with a yellow right triangle separating said field, and there are seven full five-pointed white stars and two half stars top and bottom along the hypotenuse of the triangle.

The three points of the triangle stand for the three main ethnic groups (or "constituent peoples") of Bosnia and Herzegovina: Bosniaks, Croats, and Serbs.

[3] The stars, representing Europe, are meant to be infinite in number and thus they continue from top to bottom.

The flag of the Kingdom of Bosnia was based on coat of arms of the Bosnian dynasty Kotromanić, king Tvrtko I and his successors.

The green flag with the white crescent and star pointing to the left was used by Bosniak landlords in border parts in southern and western Herzegovina.

It differs from Ottoman flag by size and direction of crescent, as well as its swallow-shape, similar to some West-European jacks and ensigns.

The coat of arms is one of Stjepan Vukčić Kosača, Bosnian noble and duke from 14th century.

The original medieval coat of arms had a white background and two red stripes in the top of the shield.

[6] Without constitutional recognition, the mid-war Federal State of Bosnia and Herzegovina first adopted the flag flown by Bosnian-Herzegovinian Partisans during the war—a wholly red flag with a narrowly gold-bordered red star in its centre, both symbolizing socialism and communism.

[citation needed] Wide public discussion ahead of constitutional adoption resulted in the overall opinion that the state flag should be red, like the one initially flown by liberation movements, and not in national pan-Slavic tricolors of Serbs and Croats which were argued to have been an "import" from a later stage of the war.

[6] In the real-world usage, this flag had a variant with a much larger canton which was offset from the edges and bordered in white.

[6] Bosnia and Herzegovina also had a new coat of arms during Yugoslav rule; it was a symbol of Bosnian industrialism at the time.

The current flag was introduced by the UN High Representative Carlos Westendorp after the Parliament of Bosnia and Herzegovina could not decide on a solution that was acceptable to all parties.

It would also use the United Nations light blue color; however, there would be the addition of a white outline map of Bosnia and Herzegovina.

Instead it had a horizontal tricolor pattern of blue, white, and red (from top to bottom), similar to that of the former Yugoslavia.
