Carnival in Brazil originated from Greek and Roman festivals and was brought to Brazil by the Portuguese in the 17th century. It evolved into a street celebration with music and dancing. Samba music and dance have African origins and were popularized in the early 20th century when the government began funding samba schools. These schools organize elaborate performances where women dance samba wearing colorful costumes. Rio de Janeiro holds large parades during Carnival with decorated floats, dancers, and music that attract thousands of spectators and tourists.
