The Portuguese had sugar plantations in Madeira and Cape Verde which utilized African slave labor. However, the first successful slave rebellion took place in Haiti, a French colony, leading to the establishment of an independent nation in 1804.
The Portuguese had their sugar plantations primarily in the islands of Madeira and Cape Verde. These were two of the early places where Europeans established sugar plantations using African slave labor. The colonial rulers had massive plantations where they cultivated sugar for export. However, these were not the places where slaves first rebelled against European rule and established an independent nation. That particular event happened in Haiti, which was a French colony and not governed by the Portuguese. It was the slaves in Haiti who were the first to successfully revolt against their European rulers and establish an independent country in 1804.
