Who Are the Mapuche? History, Culture, and Health

The Mapuche are the largest indigenous group in South America’s southern cone, with approximately 1.8 million people living primarily in south-central Chile and smaller communities in Argentina. Their name comes from their own language: “mapu” means land and “che” means people. That connection to the land isn’t just a name. It’s the organizing principle of their culture, spirituality, and centuries of political resistance.

Where the Mapuche Live

Mapuche territory stretches along the Andes Mountain range in south-central Chile and into parts of western Argentina, with the Bío-Bío River forming a traditional northern boundary. Before Spanish colonizers arrived in 1541, the Mapuche numbered about two million and occupied a vast stretch of the continent’s southern cone. Today their population in Chile alone is roughly 1.8 million, making them by far the country’s largest indigenous group. Many live in the Araucanía region, though significant numbers have migrated to cities like Santiago and Temuco over the past century.

Centuries of Resistance

What sets the Mapuche apart in the history of colonialism is how long they held their ground. While the Spanish conquered the Aztec and Inca empires within years, the Mapuche resisted colonial domination for over three centuries. The conflict, known as the Arauco War, began almost immediately after the Spanish established settlements in their territory.

In 1553, a Mapuche leader named Lautaro, who had previously served as an auxiliary to the Spanish and learned their military tactics, was appointed war leader. He assembled a force of 6,000 warriors and defeated the Spanish garrison at the fort of Tucapel, then turned captured Spanish weapons against a counterattack led by conquistador Pedro de Valdivia. Lautaro later attempted to besiege Santiago itself but was ultimately stopped by a smallpox epidemic that swept through his forces. His military brilliance inspired Mapuche revolts for generations and ensured the Araucanía region remained a stronghold of Mapuche sovereignty well into the 19th century.

Chile didn’t gain effective control over Mapuche territory until the 1880s, through a military campaign called the “Occupation of Araucanía.” That campaign displaced communities from ancestral lands and confined them to smaller reservations, setting the stage for conflicts that continue today.

Spiritual Life and the Role of the Machi

Mapuche spirituality is rooted in the land itself. In their worldview, the cosmos is organized into three interconnected layers: Wenu Mapu (the land above), where beneficial deities and ancestors reside; Nag Mapu (the land below the sky), where all living beings exist; and Minche Mapu (the land underneath), home to both good and evil spirits. These layers are held in balance, and maintaining that equilibrium is central to Mapuche life.

The most important spiritual figure is the Machi, a healer and religious leader who serves as a mediator between the community and Ngünechen, the deity who governs nature and life. Especially in rural areas, families turn to the Machi for both prayer ceremonies called Ngillatun and healing rituals called Machitun. Each Machi designs their own kultrung, a ritual drum whose circular shape symbolizes the world’s infinity. The drum’s surface is divided by a cross representing the four directions and their corresponding spiritual forces, while inside it contains small bright stones believed to be stars given by Ngünechen to empower the Machi during ceremonies.

Becoming a Machi involves an initiation where the person’s tongue is pierced while the drum-maker draws the design of the rainbow and the four parts of the world. The new Machi then receives the spiritual energy to walk the path of healing.

Traditional Medicine and Plant Knowledge

Mapuche communities have a deep ethnobotanical tradition that goes well beyond spiritual practice. Research with Mapuche-Tehuelche communities in Patagonia has documented dozens of medicinal plants used for everything from digestive problems to respiratory illness to pain relief. One of the most culturally significant is nalca (a large-leafed plant found near water), used for gastrointestinal, respiratory, and cardiovascular complaints. Ñamkulawen, a valerian species found on rocky slopes, treats a similarly broad range of conditions.

Some plants hold particular spiritual importance. Species classified as “alwe lawen,” or medicines for the souls of the dead, include rosemary, rue, and wormwood. These are considered “füre lawen,” meaning strong, bitter, potent medicines. The Mapuche system of categorizing plants relies heavily on sensory qualities like aroma and taste, with healers grouping plants by whether they smell “scented,” “minty,” or “like boldo,” a well-known South American medicinal tree used for digestive ailments.

A Language Under Pressure

The Mapuche language, called Mapuzugun (also spelled Mapudungun), is in a precarious state. Of the 1.8 million Mapuche in Chile, only about 250,000 speak the language at all, and that number includes people with passive competence who can understand Mapuzugun but not speak it fluently. The language has been steadily marginalized, losing ground in social settings and especially within the education system, which has historically operated entirely in Spanish.

Revitalization efforts face two critical challenges. The first is intergenerational transmission: if parents and grandparents stop speaking the language at home, children never acquire it naturally. The second is social attitudes, meaning whether younger Mapuche see value in learning and using the language in their daily lives. Mapuche elders point to women as playing a particularly active role in language recovery, and they emphasize an educational model centered on oral tradition rather than classroom instruction. UNESCO has classified Mapuzugun among languages needing revitalization support.

Poverty and Inequality

The Mapuche face sharp economic disparities compared to non-indigenous Chileans. Data from a national study of schoolchildren across three poverty levels tells a striking story: in areas classified as extreme poverty, 91.3% of Mapuche households were poor, compared to 64.1% of non-indigenous households. In medium-poverty areas, the gap was even more dramatic in relative terms, with 51.6% of Mapuche households in poverty versus 14.5% of non-indigenous ones. Even in the least impoverished areas, 15.5% of Mapuche families were poor compared to just 1.2% of their non-indigenous neighbors.

These numbers reflect a pattern of structural disadvantage tied directly to land loss, limited access to education, and the economic marginalization that followed the 19th-century military occupation of their territory.

Health Risks Linked to Ancestry

Mapuche populations carry a notably elevated risk of gallbladder cancer, one of the most lethal cancers due to late detection. A genetics study published in PLOS Genetics found that each 1% increase in Mapuche ancestry corresponded to a 3.7% increase in gallbladder cancer mortality risk. This association was specific to Mapuche ancestry rather than Native American ancestry broadly, suggesting a distinct genetic component. The same study found that increasing Mapuche ancestry was also linked to higher rates of stomach and esophageal cancers, but interestingly, to lower mortality from diabetes, bladder cancer, and lung cancer.

The Fight Over Land

Land remains the most volatile issue in Mapuche politics. In 1993, Chile passed Law 19.253, known as the Indigenous Law, which created CONADI, an indigenous development agency with eight elected indigenous representatives. The law included protections that barred the relocation of indigenous communities without their consent and required that any lost land be compensated with equivalent land rather than money. On paper, these were meaningful protections.

In practice, the law recognized indigenous peoples only as “ethnic groups” rather than nations and failed to address territorial demands in any comprehensive way. It took a narrow view of property rights, largely ignoring claims based on ancestral use. Meanwhile, private investment in Mapuche territories intensified. Today, forestry companies hold more than 280,000 of the roughly 435,000 hectares in the disputed Araucanía region. A single company, the CMPC holding group, controls 170,000 hectares there.

Mapuche movements have consistently pushed for three core demands: recognition of Chile as a plurinational state, the right to self-determination and autonomy, and the restitution of ancestral lands. The UN Committee on Economic, Social and Cultural Rights has expressed concern over Chile’s unsettled indigenous land claims and the lack of constitutional recognition of indigenous peoples. Chile’s recent constitutional process raised hopes for progress on these issues, though the path to meaningful legal change remains contested.
