In Brazil, an Indigenous territory or Indigenous land ( , TI) is an area inhabited and exclusively possessed by Indigenous people. Article 231 of the Brazilian Constitution recognises the inalienable right of Indigenous peoples to lands they "traditionally occupy"Defined as those lands "on which they live on a permanent basis, those used for their productive activities, those indispensable to the preservation of the environmental resources necessary for their well-being and for their physical and cultural reproduction, according to their uses, customs and traditions."Federal Constitution of Brazil. Chapter VII Article 231 . and automatically confers them permanent possession of these lands.

A multi-stage demarcation process is required for a TI to gain full legal protection, and this has often entailed protracted legal battles. Even after demarcation, TIs are frequently subject to illegal invasions by settlers and mining and logging companies.

By the end of the 20th century, with the intensification of Indigenous migration to Brazilian cities, urban Indigenous villages were established to accommodate these populations in urban settings.

Historically, the peoples who first inhabited Brazil suffered numerous abuses from European colonizers, leading to the extinction or severe decline of many groups. Others were expelled from their lands, and their descendants have yet to recover them. The rights of Indigenous peoples to preserve their original cultures, maintain territorial possession, and exclusively use their resources are constitutionally guaranteed, but in reality, enforcing these rights is extremely challenging and highly controversial. It is surrounded by violence, corruption, murders, land grabbing, and other crimes, sparking numerous protests both domestically and internationally, as well as endless disputes in courts and the National Congress.

Indigenous awareness is growing, the communities are acquiring more political influence, organizing themselves into groups and associations and are articulated at national level. Many pursue higher education and secure positions from which they can better defend their peoples' interests. Numerous prominent supporters in Brazil and abroad have voluntarily joined their cause, providing diverse forms of assistance. Many lands have been consolidated, but others await identification and regularization. Additional threats, such as ecological issues and conflicting policies, further worsen the overall situation, leaving several peoples in precarious conditions for survival. For many observers and authorities, recent advances—including a notable expansion of demarcated lands and a rising population growth rate after centuries of steady decline—do not offset the losses Indigenous peoples face in multiple aspects related to land issues, raising fears of significant setbacks in the near future.

, there were 724 proposed or approved Indigenous territories in Brazil, covering about 13% of the country's land area. Critics of the system say that this is out of proportion with the number of Indigenous people in Brazil, about 0.83% of the population; they argue that the amount of land reserved as TIs undermines the country's economic development and national security.

Definition

Jurists distinguish between Indigenous lands in a broad sense and Indigenous lands in a strict sense. Strictly speaking, Indigenous lands are those defined in the 1988 Constitution as traditionally occupied. In a broader sense, they include those defined in the of 1973, which encompasses traditionally occupied lands, reserved lands (with four categories), and community-owned lands.Almeida, Alfredo W. B. de. "Terras Tradicionalmente Ocupadas: Processos de territorialização e movimentos sociais". [Traditionally Occupied Lands: Territorialization processes and social movements] (in Portuguese) In: Revista Brasileira de Estudos Urbanos e Regionais, 2004; 6 (1):9–32

The Constitution guarantees Indigenous peoples possession of the lands they traditionally or ancestrally inhabit, regardless of their location, with no room for disputes over the feasibility or appropriateness of demarcation as established.Funai. "As Terras Indígenas" [Indigenous Lands] (in Portuguese) . However, such disputes are common, as seen in the demarcation of the Raposa Serra do Sol Indigenous Territory. Only Indigenous lands in the constitutional sense, those traditionally occupied, are subject to the demarcation process. In contrast, a reserved Indigenous land is one allocated by the federal government based on its discretion, which may be subject to judicial review, including considerations of viability and national security. These lands have four categories: Indigenous reserve, Indigenous park, Indigenous agricultural colony, and Indigenous federal territory. Community-owned lands (or proprietary lands) are those owned, not merely possessed, by Indigenous peoples, acquired through purchase or donation.

According to Lívia Mara de Resende's analysis, all these categories are controversially defined, and their practical application has sparked numerous disputes. There is uncertainty about whether the constitutional provisions for Indigenous lands—such as their inalienability, unavailability, and immunity to adverse possession—apply to reserved lands and community-owned lands. It is also debated whether the special rules in the Indian Statute for Indigenous lands in the broad sense, such as their immunity to adverse possession, remain applicable, given that reserved and community-owned lands are not considered Indigenous lands under the constitutional definition.

History and legal framework

Context of the conquest

The first humans to inhabit what would become Brazil arrived thousands of years ago. They established deep roots, developed diverse and rich cultures, and by 1500, an estimated 2 to 5 million people lived there.Povos Indígenas no Brasil. "População indígena no Brasil". [Indigenous population in Brazil] (in Portuguese) Instituto Socioambiental. That year, however, European conquerors, the Portuguese, reached the coast. Initial contacts appeared friendly, as described in the Letter of Pero Vaz de Caminha, and assistance from some tribes was crucial for the survival of many expeditions and early Portuguese settlements, fostering extensive trade and cooperation on various levels. Some Portuguese were so captivated by the Indigenous way of life that they "went native," living in the forests among them, forming families, and producing descendants, or adopting certain Indigenous customs.

Soon, however, the true intentions of the conquest became evident and increasingly dire. Imposing dominance by any means, the Portuguese subjected the land's original inhabitants to systematic abuses, including mass murders, torture, and rape, driving survivors deeper into the remote interior. In their wake, they built an entirely distinct civilization and a vast state, where Indigenous peoples were deemed an inferior and incapable race, destined by God to be subdued by the sword and, perhaps, aided by Portuguese culture under the banner of Christ. Despite the grandeur and charity embedded in such concepts, they generally served only the Portuguese. They incited rival Indigenous groups to wage war against each other for indirect benefits, used others repeatedly as allies against pirates and French and Dutch invaders, and allowed many villages to exist solely to mark new Portuguese frontiers and, above all, defend them, in the context of territorial expansion beyond Spanish domains and the limited military forces deployed to Brazil. Virtually the entire modern Brazilian Amazon, west of the Tordesillas Line, resulted from the permanent establishment of Indigenous villages transformed into Portuguese strongholds. These involuntary spearheads, such as the Macushi and Wapishana of Roraima, were called the "ramparts of the wilderness".Cunha, Manuela Carneiro da. "O futuro da questão indígena". [The future of indigenous issues] (in Portuguese) In: Estudos Avançados, 1994; 8 (20).

Massacres of resistant and hostile groups, as noted, were frequent, including those during the Guaraní War, the Tamoyo Confederation, the Potiguar revolts, and the Barbarian War, despite various royal and ecclesiastical decrees condemning such abuses. A large population ended their lives as slaves, serving the Portuguese in households, labor, and militias. After importing African slaves became more profitable, interest in Indigenous labor waned, as they were deemed rebellious and lazy. No longer serving a primary purpose, they became primarily an inconvenience to all.

Many Portuguese were horrified by the atrocities and sought to defend the Indigenous peoples, and since 1537, the Catholic Church recognized them as "true men". In practice, however, for a long time, the original peoples were often considered brute beings, insensitive to reason, justice, true faith, and noble sentiments, closer to animals than humans, with many doubting they possessed a soul. Throughout colonization, Europeans undertook numerous initiatives to "tame" native peoples and find some "utility" for the colonial project, "for the benefit of His Highness and the Kingdom," settling them in reductions or permanent villages akin to towns and assimilating them into Western civilization. They were taught the religion and customs of the colonizers, always under the assumption that their culture was worthless and should be replaced by a "superior" one, which also promised salvation and eternal life after death. They were seen as blank slates to be written upon at will, as described by Nóbrega, who was nonetheless one of their notable defenders. But violence and neglect were not the only tolls: vast populations were decimated by diseases from overseas, such as influenza, measles, whooping cough, tuberculosis, and smallpox, against which their bodies had no natural immunity, and others, addicted to aguardente, a distilled spirit widely distributed by the Portuguese, were ravaged by alcoholism.

The conquest's impact was profound not only on the original peoples but also on the natural landscape, with extensive deforestation and other environmental changes. In the words of former FUNAI president Carlos Marés de Souza Filho,

"The Europeans, especially the Portuguese and Spanish, arrived in America as if expanding their agricultural frontiers. They extracted wealth, devastated the soil, and replaced the natural environment with one they knew and controlled. The local populations lived off what was here, eating corn or cassava, producing biju, rich meats from native animals, birds, or fish. Gradually, new foods were introduced—goats, sheep, cheeses—and new plants, like sugarcane, coffee, and beets. The introduction of new species spared neither trees nor fruits, to the point that it could be said the natural world was replaced."
