Brazilian Carnival
Carnival's roots go back to the ancient Romans and Greeks who celebrated the rites of Spring. In the Middle Ages, when the Catholic Church tried to suppress all pagan ideas, it failed when it came to this celebration. The Church incorporated the rite into its own calendar as a period of thanksgiving. The nations of Europe, especially France, Spain, and Portugal, gave thanks by throwing parties, wearing masks, and dancing in the streets. All three colonizing powers carried the tradition with them to the New World, but in Brazil it landed with a difference. The Portuguese had a taste for abandoned merriment, they brought the entrudo, a prank where merry-makers throw water, flour, face powder, and many other things at each other's faces.
Prior to 1840, the streets of Brazilian towns ran riot during the three-day period leading up to Ash Wednesday with people in masks hurling stink bombs and squirting each other with flour and strong-smelling liquids; even arson was a form of entertainment. In 1840, the Italian wife of a Rio de Janeiro hotel owner changed the carnival celebration forever by sending out invitations, hiring musicians, importing streamers and confetti, and giving a lavish masked ball. In a few years the masked ball became the fashion and the wild pranks played on the streets disappeared.
