The flag of Belize was adopted on 21 September 1981, the day Belize became independent. It consists of the Coat of Arms on a blue field with red stripes at the top and bottom.
British Honduras obtained a coat of arms on 28 January 1907, which formed the basis of the badge used on British ensigns. The coat of arms recalls the logging industry that first led to British settlement there. The figures, tools, and mahogany tree represent this industry. The national motto, Sub Umbra Floreo, meaning "Under the Shade I Flourish", is written in the lower part of the coat of arms. The colors on the flag are respectively those of the country's national parties, the People's United Party (PUP) and United Democratic Party (Belize) (UDP). The UDP, established in 1973, had objected to the original blue and white design, those two colors being the PUP's representative colors.
The two red stripes at the top and bottom were added to the original design at independence. The coat of arms was granted in 1907. Red stripes were added to denote the color of the opposition party. The 50 leaves recall 1950, the year PUP came to power.
