The Portuguese Empire, also known as the Portuguese Overseas or the Portuguese Colonial Empire, was composed of the overseas colonies, factories, and later overseas territories, governed by the Kingdom of Portugal, and later the Republic of Portugal. It was one of the longest-lived colonial empires in European history, lasting 584 years from the conquest of Ceuta in North Africa in 1415 to the transfer of sovereignty over Macau to China in 1999. The empire began in the 15th century, and from the early 16th century it stretched across the globe, with bases in Africa, North America, South America, and various regions of Asia and Oceania.
Equinoctial France was the contemporary name given to the colonization efforts of France in the 17th century in South America, around the line of Equator, before "tropical" had fully gained its modern meaning: Equinoctial means in Latin "of equal nights", i.e., on the Equator, where the duration of days and nights is nearly the same year round. The settlement was made in what is now known as the Bay of São Luis and lasted for 3 years.
The Dutch colonial empire comprised the overseas territories and trading posts controlled and administered by Dutch chartered companies—mainly the Dutch East India Company and the Dutch West India Company—and subsequently by the Dutch Republic (1581–1795), and by the modern Kingdom of the Netherlands after 1815.

The Dutch still retained a presence in Brazil until 1654 and a treaty was signed in 1661.
