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 became known as "the Soldier King". Born in Lisbon, he was the fourth child of King Dom João VI (John 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 1808, Pedro I and his family fled to Portugal's largest and wealthiest colony, Brazil. Neglected by his parents, he grew up without restraints.

Pedro was born at 08:00 on 12 October 1798 in the Queluz Royal Palace near Lisbon, Portugal. He was named after St. Peter of Alcantara, and his full name was Pedro de Alcântara Francisco António João Carlos Xavier de Paula Miguel Rafael Joaquim José Gonzaga Pascoal Cipriano Serafim. He was referred to using the honorific "Dom" (Lord) from birth.

Through his father, Prince Dom João (later King Dom João VI), Pedro was a member of the House of Braganza (Portuguese: Bragança) and a grandson of King Dom Pedro III and Queen Dona (Lady) Maria I of Portugal, who were uncle and niece as well as husband and wife. His mother, Doña Carlota Joaquina, was the daughter of King Don Carlos IV of Spain. The marriage of Pedro's parents was an unhappy one. Carlota Joaquina was an ambitious woman, who always sought to advance Spain's interests, even to the detriment of Portugal's. Reputedly unfaithful to her husband, she went as far as to plot his overthrow, in league with dissatisfied Portuguese nobles.

Brazil ⁱ/brəˈzɪl/ (Portuguese: Brasil, IPA: [bɾaˈziw]), officially the Federative Republic of Brazil (Portuguese: República Federativa do Brasil,  listen (help·info)), is the largest country in South America. It is the world's fifth largest country, both by geographical area and by population with over 192 million people. It is the only Portuguese-speaking country in the Americas and the largest lusophone country in the world.

Bounded by the Atlantic Ocean on the east, Brazil has a coastline of 7,491 km (4,655 mi). It is bordered on the north by Venezuela, Guyana, Suriname and the French overseas region of French Guiana; on the northwest by Colombia; on the west by Bolivia and Peru; on the southwest by Argentina and Paraguay and on the south by Uruguay. Numerous archipelagos form part of Brazilian territory, such as Fernando de Noronha, Rocas Atoll, Saint Peter and Paul Rocks, and Trindade and Martim Vaz. It borders all other South American countries except Ecuador and Chile.

Brazil was a colony of Portugal from the landing of Pedro Álvares Cabral in 1500 until 1815, when it was elevated to the rank of kingdom and the United Kingdom of Portugal, Brazil and the Algarves was formed. The colonial bond was in fact broken in 1808, when the capital of the Portuguese colonial empire was transferred from Lisbon to Rio de Janeiro, after Napoleon invaded Portugal.Independence was achieved in 1822 with the formation of the Empire of Brazil, a unitary state governed under a constitutional monarchy and a parliamentary system. The country became a presidential republic in 1889, when a military coup d'état proclaimed the Republic, although the bicameral legislature, now called Congress, dates back to the ratification of the first constitution in 1824. Its current Constitution, formulated in 1988, defines Brazil as a Federal Republic. The Federation is formed by the union of the Federal District, the 26 States, and the 5,564 Municipalities.

David Luiz Moreira Marinho (born 22 April 1987), known as David Luiz, is a Brazilian footballer who plays for Chelsea in the Premier League. Primarily a central defender, he can also be deployed as a left back.

After starting out at Vitória, he moved to Benfica at the age of 19, remaining with the club five seasons (three complete). He joined Chelsea in January 2011, winning the Champions League and the FA Cup in the following season.

Born in Diadema, São Paulo, David Luiz arrived in Esporte Clube Vitória at the age of 14 after being released by São Paulo FC, and started playing as a defensive midfielder, almost leaving the club for his poor performances in that position. However, he was soon moved to central defender and adapted well.

Luiz made his official debut for Vitória in 2006, and excelled against Santa Cruz Futebol Clube for that season's Brazilian Cup, in a 2–2 draw. At the worst situation of its history, in the third division, Vitória promoted to the second division at the end of the season with Luiz's help, after finishing in second position, with the central appearing in eight of the club's last decisive nine games, scoring his only Série C goal on 3 September 2006, in a 2–0 home win against Clube Atlético do Porto.

Dom Pedro II (English: Peter II; 2 December 1825 – 5 December 1891), nicknamed "the Magnanimous", was the second and last ruler of the Empire of Brazil, reigning for over 58 years. Born in Rio de Janeiro, he was the seventh child of Emperor Dom Pedro I of Brazil and Empress Dona Maria Leopoldina and thus a member of the Brazilian branch of the House of Braganza. His father's abrupt abdication and flight to Europe in 1831 left a five-year-old Pedro II as Emperor and led to a grim and lonely childhood and adolescence. Obliged to spend his time studying in preparation for rule, he knew only brief moments of happiness and encountered few friends of his age. His experiences with court intrigues and political disputes during this period greatly affected his later character. Pedro II grew into a man with a strong sense of duty and devotion toward his country and his people. On the other hand, he increasingly resented his role as monarch.
