The flag of the Federal District of Brasilia was instituted by decree on 25 August 1969. It was designed by the poet Guilherme de Almeida, an authority on heraldry. The target symbolizes peace, while the four arrows in the form of a cross connect with the indigenous tradition of the four cardinal points of the compass.
The flag of the Federal District was instituted by decree no. 1090 of 25 August 1969. It is the white field that represents peace, while the green rectangle and the yellow cross (made of four arrows) refer to the national colors. The cross has a lozenge in the center formed by the feathers of the arrows, another reference to the national flag. The arrows are an allusion to the arrows of the indigenous peoples and indicate "the centrifugal action of power" emanating toward the four cardinal points of the compass. The cross also symbolizes the Southern Cross, the cross carried by the explorer Cabral, and Christian beliefs.
