Dom Pedro I (English: Peter I; 12 October 1798 – 24 September 1834), nicknamed "the Liberator", was the founder and first ruler of the Empire of Brazil. As King Dom Pedro IV, he reigned briefly over Portugal, where he also became known as "the Liberator" as well as "the Soldier King". Born in Lisbon, Pedro I was the fourth child of King Dom João VI of Portugal and Queen Carlota Joaquina, and thus a member of the House of Braganza. When their country was invaded by French troops in 1807, he and his family fled to Portugal's largest and wealthiest colony, Brazil.
