The Flag of Portugal (Portuguese: Bandeira de Portugal) is the national flag of the Portuguese Republic. It is a rectangular bicolour with a field unevenly divided into green on the hoist, and red on the fly. The lesser version of the national coat of arms (i.e. armillary sphere and Portuguese shield) is centred over the colour boundary at equal distance from the upper and lower edges. On June 30, 1911, less than a year after the downfall of the constitutional monarchy, this design was officially adopted for the new national flag, after selection by a special commission whose members included Columbano Bordalo Pinheiro, João Chagas and Abel Botelho.
