Samba schools used the carnival to foreground overlooked histories

I WAS RECENTLY IN RIO DE JANEIRO, IN A warehouse on the outskirts of the city, admiring some of the brightly coloured floats that had featured in this year's world-famous carnival. Each spring, just before the start of Lent, hundreds of thousands of people attend the parades in the city's Sambadrome stadium and enjoy watching the floats.

Like pieces of art many metres high, they are designed and intricately handmade in Rio's numerous escolas de samba (samba schools), each strongly identified with a local neighbourhood. The schools are organised into leagues for the carnival, during which they compete for the prestigious design award.

Pre-Lenten festivities in Brazil began in the early 18th century, during the Portuguese colonial era. The Catholic influence is evident in the name of the event, which is believed to derive from the Latin carnem vale (farewell to meat) or carnem levare (remove meat), referring to the 40-day period of abstinence leading up to Easter.

It's said that the earliest form of the festivities in Brazil evolved from the pre-Lenten Entrudo, celebrated by immigrants from other Portuguese colonies on the Azores, Madeira and Cabo Verde. During that festival, people soaked each other with buckets of water and hurled mud and food, wreaking cheery mayhem that often degenerated into street brawls.
