Argentina's flag is a light blue and white triband with a yellow "Sun of May" in the center. The flag is twice as wide as it is tall.
This flag was adopted on February 12, 1812, four years after Argentina achieved independence from Spain (1816). The "Sun of May" design was added to the flag in 1818.
The blue and white colors were chosen by Manuel Belgrano, the leader of the Argentinian revolution against Spain, and represent the blue sky parting to reveal white clouds, as is said to have happened when the Liberation demonstration began in Buenos Aires, Argentina, on May 25, 1810.
