full_context: Document 1: Lei Áurea: The Lei Áurea (] ; English: Golden Law ), adopted on May 13, 1888, was the law that abolished slavery in Brazil.

Document 2: Decree 1775: Decree 1775 was signed into Brazilian law by President Fernando Henrique Cardoso on January 8, 1996. The decree changed the steps FUNAI was required to follow to demarcate indigenous lands, effectively making the process more complicated and allowing for more interference from commercial interests. Individuals or companies were allowed from the beginning of the demarcation process until 90 days after FUNAI issued their report to submit an appeal showing that the contested lands do not meet the qualifications of indigenous lands as stated in the constitution. The decree also placed the final decision in the hands of the Minister of Justice, which left the fate of indigenous lands vulnerable to various political ideologies. The government claimed that allowing people to contest indigenous lands during the demarcation process would prevent any future challenges of completed lands on the basis of unconstitutionality. The decree was widely contested as a violation of indigenous rights, earning the nickname of the "Genocide Decree," due to the power it gave to commercial interests to exploit Indian lands. By April 1996, FUNAI had received over 500 appeals for over 40 indigenous territories that were in the process of being demarcated. FUNAI followed procedure and submitted its official opinion to the Ministry of Justice, rejecting the appeals that were brought against the indigenous lands. Justice Nelson Jobim sided with FUNAI on all except eight territories, ordering further investigation.

Document 7: Brazilian imperial family: The Brazilian Imperial Family is a royal family and cadet branch of the Portuguese Royal House of Braganza that ruled the Empire of Brazil for 67 years, between 1822 and 1889, after the proclamation of independence by Prince Pedro of Braganza who was later acclaimed as Pedro I, "Constitutional Emperor and Perpetual Defender of Brazil". The members of the family are dynastic descendants of Emperor Pedro I. Claimants to headship of the post-monarchic Brazilian Imperial legacy descend from Emperor Pedro II, including the senior agnates of two branches of the House of Orléans-Braganza; the so-called "Petrópolis" and "Vassouras" lines. Prince Pedro Carlos of Orléans-Braganza (born 1945) heads the "Petrópolis" line, while the "Vassouras" branch is led by his second cousin, Prince Luiz of Orléans-Braganza. Rivalry within the family erupted in 1946 when "Dom" Pedro Gastão (1913–2007) repudiated the renunciation to the throne of his late father, Pedro de Alcântara, Prince of Grão-Pará (1875–1940), for himself and his future descendants, when he made a non-dynastic marriage in 1908. Pedro de Alcântara was the eldest son of the Princess Imperial Isabel (1846–1921) who, as Pedro II's elder daughter and heir presumptive when he was dethroned, became the last undisputed head of the family after her father's death in exile in 1891. Pedro Carlos is "Dom" Pedro Gastão's eldest son. "Dom" Luiz descends from Isabel's younger son, Prince Luís (1878–1920) who, by a Bourbon princess, fathered Prince Pedro Henrique (1909–1981). Dom Luiz is Pedro Henrique's son by a Bavarian princess and upholds his dynastic claim to the same legacy.
