Flag of Portugal [SEP] Introduction
The flag of Portugal () is a rectangular bicolour with a field 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 centered over the colour boundary at equal distance from the upper and lower edges. On 30 June 1911, less than a year after the downfall of the constitutional monarchy, this design was officially adopted for the new national flag of the First Portuguese Republic, after selection by a special commission whose members included Columbano Bordalo Pinheiro, João Chagas and Abel Botelho.
