Dona Maria Amélia was a princess of the Empire of Brazil and a member of the Brazilian branch of the House of Braganza. Her parents were Emperor Dom Pedro I, the first ruler of Brazil, and Amélie of Leuchtenberg. The only child of her father's second marriage, Maria Amélia was born in France after Pedro I abdicated the Brazilian throne in favor of his son Dom Pedro II. Before Maria Amélia was a month old, Pedro I went to Portugal to restore the crown of the eldest daughter of his first marriage, Dona Maria II. He fought a successful war against his brother Miguel I, who had usurped Maria II's throne.

Dom Pedro I was the founder and first ruler of the Empire of Brazil, where he was known as "the Liberator". 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 John VI of Portugal and Queen Carlota Joaquina, and thus a member of the House of Braganza. When the country was invaded by French troops in 1807, he and his family fled to Portugal's largest and wealthiest colony, Brazil.
