Which historical figure does Brazil consider to be their national hero?

I live in the US and George Washington isn't a national hero to lots of people!

Tiradentes.

Pedro I of Brazil: Pedro I (pronounced [ˈpedɾu] in Portuguese; English: Peter of Alcantara Francis Anthony John Charles Xavier of Paula Michael Raphael Joaquim Joseph Gonzaga Pascal Cyprian Seraphim of Braganza and Bourbon) (full name: Pedro de Alcântara Francisco Antônio João Carlos Xavier de Paula Miguel Rafael Joaquim José Gonzaga Pascoal Cipriano Serafim de Bragança e Bourbon), known as "Dom Pedro Primeiro" (October 12, 1798 – September 24, 1834), proclaimed Brazil independent from Portugal and became Brazil's first Emperor. He also held the Portuguese throne briefly as Pedro IV of Portugal, the Soldier-King (Port. o Rei-Soldado), 28th (or 29th according to some historians) king of Portugal and the Algarves. He was also a Freemason. Brazilian Independence: When King João VI finally returned to Portugal, in the early 1820s, most of the privileges that had been accorded to Brazil were rescinded, sparking the ire of local nationalists. Pedro, who had remained in the country as regent, sided with the nationalist element and even supported the Portuguese Constitutionalist movement that led to the revolt in Porto in 1820. When pressed by the Portuguese court to return, he refused. For that, he was demoted from regent to a mere representative of the Lisbon court in Brazil. This news reached him on September 7, 1822, when he had just arrived in São Paulo, from a visit to the port of Santos. On the banks of the Ipiranga River, he unsheathed his sword, removed the blue and white Portuguese shield from his coat, and declared "Independence or death!" This later became his famous speech "O grito do Ipiranga" (The Cry of Ipiranga). He was proclaimed Emperor of Brazil on October 12, his 24th birthday, and crowned on December 1.
