Named after St. Peter of Alcantara, his name in full was Pedro de Alcântara João Carlos Leopoldo Salvador Bibiano Francisco Xavier de Paula Leocádio Miguel Gabriel Rafael Gonzaga.
Through his father, Emperor Dom Pedro I, he was a member of the Brazilian branch of the House of Braganza (Portuguese: Bragança) and was referred to using the honorific "Dom" (Lord) from birth.
He was the grandson of Portuguese King Dom João VI and nephew of Dom Miguel I. His mother was the Archduchess Maria Leopoldina of Austria, daughter of Franz II, the last Holy Roman Emperor.
Through his mother, Pedro was a nephew of Napoleon Bonaparte and first cousin of Emperors Napoleon II of France, Franz Joseph I of Austria-Hungary and Don Maximiliano I of Mexico.

The only legitimate male child of Pedro I to survive infancy, he was officially recognized as heir apparent to the Brazilian throne with the title Prince Imperial on 6 August 1826.
Empress Maria Leopoldina died on 11 December 1826, a few days after a stillbirth, when Pedro was a year old.
Two and a half years later, his father married Amélie of Leuchtenberg.
Prince Pedro developed an affectionate relationship with her, whom he came to regard as his mother.
Pedro I's desire to restore his daughter Maria II to her Portuguese throne, which had been usurped by his brother Miguel I, as well as his declining political position at home led to his abrupt abdication on 7 April 1831.
He and Amélie immediately departed for Europe, leaving behind the Prince Imperial, who became Emperor Dom Pedro II.
