Samba is the national dance of Brazil. The rhythm of samba and its name originated from the language and culture of West African slaves. In 1905, samba became known to other countries during an exhibition in Paris. In the 1940s, samba was introduced in America through Carmen Miranda. The international version of Ballroom Samba has been based on an early version of Brazilian Samba called Maxixe, but has since developed away and differs strongly from Brazilian Ballroom Samba, which is called Samba de Gafieira. International Ballroom Samba is danced with a slight bounce which is created through the bending and straightening the knee. It is performed as an International Latin dance, although most of its modern development has occurred outside Latin America.
