Flag of Brazil

The national flag of Brazil is a blue disc depicting a starry sky spanned by a curved band inscribed with the national motto Ordem e Progresso, within a yellow rhombus on a green field. It was officially adopted on 19 November 1889, four days after the Proclamation of the Republic, to replace the flag of the Empire of Brazil. The concept was the work of Raimundo Teixeira Mendes, with the collaboration of Miguel Lemos, Manuel Pereira Reis and Décio Villares.

Decree No. 4, issued on 19 November 1889, legally replaced the flag used under the constitutional monarchy with the new national flag. The last change was held on 11 May 1992, Law No. 8.421, altered the celestial globe with the addition of six stars. The precise positions of the 27 stars on the globe makes the Brazilian flag one of the most complicated national flags to construct. The official design is defined by Law No. 5,700, issued on 1 September 1971. The flag's length is twenty modules and the width, fourteen, translating into an aspect ratio of 10:7. The distance of the vertices of the yellow rhombus to the outer frame is a module and seven-tenths (1.7 m). The blue circle in the middle of the yellow rhombus has a radius of three and a half modules (3.5 m). The center of the arcs of the white band is two modules (2 m) to the left of the meeting point of the extended vertical diameter of the circle with the base of the outer frame. The radius of the lower arc of the white band is eight modules (8m) and the radius of the upper arc of the white band is eight and a half modules (8.5 m). The width of the white band is a half of a module (0.5 m). The caption "Ordem e Progresso"…
