[2] The flag was retained after Montenegrin independence from Serbia in 2006, and mandated by Article 4 of the Constitution of Montenegro adopted in 2007.

The flag of Montenegro is red, with the coat of arms in the middle, and golden borders.

Before him, the principal Montenegrin flag had been the alaj-barjak (regimental colors) with a single symbol on it – the cross (krst).

The first written description of a Montenegrin flag dates from the time of Šćepan Mali: it was white, with a red frame and a golden cross on top of the spear.

Around 1910, two new variants appeared: one tricolor (red, blue and white) with the two-headed eagle bearing the initials NI on its breast and the lion passant on the sinister, the other with the two-headed eagle above the initials NI.

The flags of several Yugoslav Republics used their traditional tricolors, with the monarchic coat of arms replaced by the red star of Communism.

The provisions relating to the flag in the 2004 Law on State Symbols were affected by subsequent amendments in 2011 and 2019.
