São Paulo´s
history
officially began on January 25, 1554
when the Jesuit missionaries Manuel da Nóbrega and José de Anchieta
celebrated a mass at today´s
Patio do Colégio in the historic center.
In the Roman Catholic calender of saints, January 25 is the feast day of the
Conversion of St. Paul.
Even 300 years after its foundation, São Paulo counted only 15.000 inhabitants, which were mostly Portuguese conqueror and African slaves.
After the abolishment of slavery at the end of the 19th century this number was increased to 240.000 by
European, Asian and Arab immigrants.
Only during the last 100 years, São Paulo´s population exploded to 11 million people (19 million in the Greater São Paulo area) representing
nowadays the most populous metropolitan area in the southern hemisphere.
