The Kingdom of Burundi became independent on the 1st of July in 1962. The in this context introduced flag is divided by a white diagonal cross into four fourth, to the left and to the right ever one green, above and below ever one red. The middle of the flag carryed a white disk with a drum (symbol for the Tutsi monarchy) and a millet plant thereupon. Green stands for the hope, red for the in the fight for independence shed blood, and white for the peace. The monarchy was unseated on the 28th of November in 1966, and was proclaimed the republic. After interim solutions the flag was changed into her today's form on 28th of July in 1967. The drum and the millet plant on the flag from 1962 got substituted by three red, green bordered, six-jagged stars. The three stars stand for the motto of the state "Unité, Travail, Progress" → "unity, work, progress", respectively for the three ethnic groups in the land, the Tutsi, Hutu and Twa. In 1982 the ratio of the flag sides was changed from 2:3 to 3:5. The colors given for the flags today are: red = pt 186, green = pt 361 and white.
The initial coat of arms from 1962 showed a red shield with a golden lion head, behind it four crossed spears, above the shield the Tutsi drum, and underneath in a ribbon the motto of the state: "Ganza Sabwa" → "govern rule". After the proclamation of the republic one of the spears and the drum got deleted , and the motto of the state was changed. The three spears refer to the three stars in the flag.
