Amador Bueno (Regnum Bueno)

Amador Bueno (c. 1584 - c. 1649) was a landowner, colonial administrator of the Captaincy of São Vicente (Colonial Brazil) and the King of São Paulo.

Bueno was born around 1584 in the city of São Paulo, Captaincy of São Vicente which is now the Province of São Vicente. He was born to Bartolomeu Bueno da Ribeira, a Spanish settler from Seville and Maria Pires, from São Paulo, daughter of Salvador Pires and Mécia Fernandes. Amador held several public office posts through royal appointment and elections.

Since 1580, the Kingdom of Portugal was in a dynastic union with the Kingdom of Spain, up until 1640, when the Portuguese acclaimed John IV of Portugal as the new king. A largely Spanish contingent in São Paulo broke away from both in 1641. Without Bueno's consent, they claimed him to be their king. Bueno finally accept the offer and was crowned the King.
