When the English captured Jamaica, most Spanish colonists fled, with the exception of Spanish Jews, who chose to remain on the island. Spanish slave holders freed their slaves before leaving Jamaica. Many slaves dispersed into the mountains, joining the already established maroon communities. During the centuries of slavery, Jamaican Maroons established free communities in the mountainous interior of Jamaica, where they maintained their freedom and independence for generations, under the leadership of Maroon leaders such as Juan de Serras.
