full_context: Document 1: Dance in Cuba: Cuban culture encompasses a wide range of dance forms. The island's indigenous people performed rituals known as areíto, which included dancing, although little information is known about such ceremonies. After the colonization of Cuba by the Spanish Kingdom, European dance forms were introduced such as the French contredanse, which gave rise to the Cuban contradanza. Contradanza itself spawned a series of ballroom dances between the 19th and 20th centuries, including the danzón, mambo and cha-cha-cha. Rural dances of European origin, such as the zapateo and styles associated with punto guajiro also became established by the 19th century, and in the 20th century son became very popular. In addition, numerous dance traditions were brought by black slaves from West Africa and the Congo basin, giving rise to religious dances such as Santería, yuka and abakuá, as well as secular forms such as rumba. Many of these dance elements from European dance and religious dances were fused together to form the basis of la técnica cubana. Cuban music also contributed to the emergence of Latin dance styles in the United States, namely rhumba (ballroom rumba) and salsa.
