Which 2 islands di the portuguse have thier sugar plantions

Madeira and Cape Verde were the two islands the Portuguese have their sugar plantations. During the fifteenth century, Portuguese travelers established a variety of proto-colonies along the coast of Africa, mainly to exploit the growing sugar industry that would soon produce great wealth for European traders.
