Capoeira is a Brazilian martial art created by enslaved Africans during the 16th Century. It originated by Nigerian or Angolan ethnic groups where members fought with music and the winner won a partner, usually female. Participants form a roda (circle) and take turns playing instruments, singing, and sparring in pairs in the centre of the circle. The game is marked by fluid acrobatic play, feints, subterfuge, and extensive use of groundwork, as well as sweeps, kicks, and headbutts. Technique and strategy are the key elements to playing a good game.
