The Carnival of Brazil is an annual festival held 46 days before Easter, especially famous for the Carnival in Rio de Janeiro. Carnival celebrations are believed to have roots in the festival of Saturnalia, which, adapted to Christianity, became a farewell to bad things in a season of religious discipline to regret and prepare for Christ’s death and coming back to life.

Modern Brazilian Carnival dates back to Rio de Janeiro in 1641. It originally copied the European form of the festival, later taking in elements of Native American and African cultures.

In the late 19th century, the strings (弦乐器) were introduced in Rio de Janeiro. These were pageant (游行) groups that paraded through city avenues performing on instruments and dancing. Today they are known as blocks, consisting of a group of people who dress in costumes or special T-shirts with themes or logos. Blocks are generally connected with particular neighborhoods; they include both a music group and a lot of revelers.

Block parades have become an expressive feature of Rio’s Carnival. Today, they number more than 100 and the groups increase each year. Blocks can be formed by small or large groups of revelers with a clear title. Before the show, they gather in a square, then parade in sections of the city, often near the beach.

Carnival time in Rio is very interesting, but is also the most expensive time to visit Rio. Hotel rooms and other lodgings (住宿) can be up to four times more expensive than the regular rates. There are big crowds at some locations and life is far from ordinary in many parts of town.
