The Belgians are in Brazil since colonial times. Some of the early settlers and bandeirantes from São Paulo were Belgians or had Belgian forefathers (most of them were flemings), like Cornélio de Arzam, Pedro Taques (his father was a merchant from Brabant), Fernão Dias Pais Leme (the Leme family established itself in Portugal in the late 15th century through a merchant named Martim Leme; his descendants came to São Vicente in the beginning of the colonization of Brazil), and probably Jacques Félix (it is likely that his father was also named Jacques Félix, nicknamed "the Flemish", who was from Flanders and established himself in Santos in the early 16th century). All this settlers and their relatives had huge descent, spreading throughout the southern and central Brazil. Today it is still common to find these surnames (Leme, Taques etc.) in the interior of São Paulo state and neighboring states, through people who are descendant of those settlers.
With the independence of the country in 1822, Belgians kept coming through immigration. Many colonies were founded during the 19th century, specially in Southern Brazil, but also in São Paulo, Minas Gerais, Espirito Santo and Rio de Janeiro.
