Cuban Spanish is most similar to, and originates largely from, the Spanish that is spoken in the Canary Islands and Andalusia. Cuba owes much of its speech patterns to the heavy Canarian migrations of the 19th and early 20th centuries. The accent of La Palma is the closest of the Canary Island accents to the Cuban accent. Many Cubans and returning Canarians settled in the Canary Islands after the revolution of 1959. Migration of other Spanish settlers (Asturians, Catalans, Galicians and Castilians) also occurred, but left less influence on the accent.
