Carnival in Rio de Janeiro is a world famous festival held before Lent every year and considered the biggest carnival in the world with two million people per day on the streets. The first festivals of Rio date back to 1723.
The carnival parade is filled with people and floats from various samba schools. A samba school can either be an actual school or just a collaboration of local neighbours that want to attend carnival. Samba schools include: Uniao de Sonhadores, Mocidade Independente, Imperio Serrano, Academicos do Salgueiro, Unidos da Tijuca, and Beija-Flor de Nilopolis.

The purpose of carnival is for samba schools to compete with fellow rival schools; this competition is the climax of the whole carnival festival. Each school chooses a theme to try and portray in their entry. The samba schools work to build the best floats and costumes to represent their themes, and to include the best music they can from their band called the bateria.There are many parts to each school's entry including the six to eight floats and thousands of participants.
