Since 1808-1815 they were no longer colonies and had the same status as the metropole; they even sent delegates to the Cortes. Dom Pedro was already an autonomous ruler in the New World.

Besides the bicentennials, this year also has notable centennials:
>February 13th-17th, 1922: Modern Art Week in São Paulo
(Used as a landmark for the Modernist movement but arbitrary, Modernism already existed)
>March 25th, 1922: founding of the Communist Party
(Most of the old Communist Parties were founded around this time after the Russian Revolution)
>July 5th, 1922: first of the 1920s lieutenant revolts
(Only famous because it happened in Copacabana, the 1924 revolt in São Paulo had terror bombing, urban warfare and hundreds of thousands of refugees and yet nobody cares)
