Explanation:

1- The colonization of Brazil began in 1500 with the arrival of seafarer Pedro Alvares Cabral, who proclaimed Brazil a Portuguese colony. The Brazilian north coast fell under Dutch colonial rule for some time in the 17th century. The Portuguese Crown, however, steadily expanded its rule and in 1808 the Portuguese court moved from Lisbon to Rio de Janeiro. Brazil then became the pivot in the United Kingdom of Portugal, Brazil and the Algarve and declared its independence in 1822. The connection with the Portuguese royal family was maintained for several decades in the Empire of Brazil, but was definitively broken with the Proclamation of the Republic in 1889.

2- The arrival of Europeans in the fifteenth century changed the lives of the peoples of America. Among the hundreds of nations that populated the continent, many have disappeared or been exterminated. The demographic disaster is due mainly to epidemics, but also to wars, forced labor, displacement of entire tribes. The Indian population in Latin America rose, according to estimates, from 30 to 80 million inhabitants during the "discovery" of America by Christopher Columbus to 4.5 million a century and a half later.

3- The Treaty of Tordesillas governed the division of the non-European world between Castile and Kingdom of Portugal, which organized the first voyages of discovery. The treaty was ratified by Castile on 2 July 1494 and by Portugal on 5 September 1494.
