Flag of Montenegro
The flag of Montenegro () has a red field with gold border and the coat of arms of Montenegro in its center. It was officially adopted on 13 July 2004, when the then Republic of Montenegro was a constituent of the State Union of Serbia and Montenegro, and its precise specification was standardized on 16 September 2004. The flag was retained after Montenegrin independence in 2006, and mandated by Article 4 of the Constitution of Montenegro adopted in 2007. Description. The flag of Montenegro is red, with the coat of arms in the middle, and golden borders. The  ratio of the flag is 1:2. The coat of arms takes up of the flag's height. The middle point of the coat of arms matches the middle point of the flag. The width of the border is of the flag's proportions. Two versions of the Montenegrin flag are in use, horizontal, mostly used outdoor; and vertical, mostly used indoor. Use of flag. The flag is permanently hoisted on: The flag is also hoisted on: The flag may also be hoisted during international meetings, political, scientific, cultural, artistic, sporting and other manifestations in which Montenegro is represented, according to  the rules of such events. According to international tradition, when the flag is hoisted together with one or more flags of other states or international organizations on Montenegrin soil, the flag takes the place of honour. The place of honour is considered the center of a circle, the top of a semicircle, the first place in a row, column or a group of flags, the central position between the flags and the left side as seen from the front from the flags of other states or international organizations. The flag is hoisted, lowered and carried with the usual honors (standing  up, saluting etc.) The flag can not be hoisted so as to touch the ground, nor should be used as a table cloth, curtain or similar. Historical. The historical war flags were the krstaš-barjak, plain flags with crosses in the center. Flags as the state symbols were introduced only in the time of Petar II Petrović-Njegoš. 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. The next comes from 1838: pale-yellow with the small red cross, and in 1876 the flag was described as red with a white cross. At the time of Prince Danilo, the cross on the alaj-barjak was replaced by the two-headed eagle with the initials DI (Danilo I) on its breast, with the lion passant underneath. Prince/King Nikola used many different flags in his time. The first of the variants was the same as Danilo's, differing only in the initials – NI (Nikola I). 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". In late 1946 a new flag was adopted for the People's Republic [PR, later SR] of Montenegro as a constituent republic of the Federal People's Republic [FPR, later SFR] of Yugoslavia. The flags of several SFR Yugoslav Republics used their traditional tricolors, with the monarchic coat of arms replaced by the Red Star of Communism. The replacement left  the flags of SR Serbia and SR Montenegro identical. After the 1991–1992 breakup of SFR Yugoslavia, a noncommunist "rump" Federal Republic [FR] of Yugoslavia was formed by the Republic of Serbia and Republic of Montenegro. In 1993 the latter adopted as its flag a horizontal tricolor of red, light blue and white, with the size ratio of 1:3, making it the widest national flag in the world. Increased Montenegrin nationalism saw FR Yugoslavia replaced in 2003 by the looser State Union of Serbia and Montenegro, which failed to prevent a 2006 Montenegrin independence referendum precipitating the dissolution of the union . During this period, in 2004 the Assembly of the Republic of Montenegro passed the "Law on State Symbols and the Day of the Statehood of Montenegro". It was promulgated in the official gazette on 12 July 2004 and came into force the following day, which was proclaimed Statehood Day. The July law gave the government 60 days to produce a comprehensive specification; in fact this was finalized on 16 September 2004 and published the next day. In the interim, some flag manufacturers had interpreted the July law's "gold border" as a fringe rather than a bordure; the latter interpretation  was confirmed by the September specification. The flag is mandated by Article 4 of the Constitution of Montenegro adopted in 2007. The provisions relating to the flag in the 2004 Law on State Symbols were affected by subsequent amendments in 2011 and 2019. An updated flag protocol was published in 2020.
