Flag of Brazil

The flag of Brazil, known in Portuguese as Verde e amarela, or less usually Auriverde, 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. Brazil officially adopted this design for its national flag on November 19, 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.

The green field and the yellow parallelogram from the previous imperial flag, though slightly modified in hue and shape, were preserved — the green represented the House of Braganza of Pedro I, the first Emperor of Brazil, while the yellow represented the House of Habsburg of his wife, Empress Maria Leopoldina.
