Violent history of uncontacted tribe forced to make worrying move as experts issue warning

One of the largest uncontacted tribes in the world might be under threat, following their long and violent history of defending their territory.

The Mashco Piro are an Indigenous people of southeast Peru, with 750-plus individuals, according to Survival International

They typically live in and around the Madre de Dios Territorial Reserve, moving seasonally along the river to avoid sustained contact with outsiders.

Their isolation is historically considered to be a response to violent encounters during the late-19th-century rubber boom.

During the Amazon rubber boom, barons like Carlos Fitzcarrald led dangerous expeditions into Mashco Piro territory.

This often involved massacres, enslavement, and forced displacement, as survivors would flee deeper into the forest. It's one reason why the Mashco Piro remain hostile to outsiders to this day.

Throughout the 20th century, there has been repeated raids and violent clashes with river traders and settlers.

The Mashco Piro - who became feared locally for ambushes on intruders - killed tour guide Nicolás 'Shaco' Flores in 2011.

He had been bringing food and tools to the people, but was shot down by arrows while approaching them on a riverbank.

Then in 2015, at least one villager was killed during confrontations along the Manu River.

There were more reported clashes between Mashco Piro and loggers operating inside, or possibly near their reserve, after two loggers who entered the territory were killed in a bow and arrow attack last summer.

Construction of a logging bridge by Maderera Canales Tahuamanu led to sightings of Mashco Piro entering or approaching a Yine village.

Though no fatalities have yet been reported, residents and groups fear imminent issues if logging continues.

The Amazon logging industry poses a threat to Indigenous communities through land invasion, possible violence, and even disease exposure.

For uncontacted groups like the Mashco Piro, contact with loggers risks deadly epidemics and territorial loss.

“Exactly one year after the encounters and the deaths, nothing has changed in terms of land protection and the Yine are now reporting to have seen both the Mashco Piro and the loggers exactly in the same space almost at the same time,” warned Teresa Mayo, a researcher at Survival International. “The clash could be imminent.”

As reported by The Guardian, she added: “They still have the license of the government, and that is how they back their activities even if they know they are putting both Mashco Piro and their workers’ lives at risk.”

Enrique Añez, president of the nearby Yine community, another Indigenous group, said: “It is very worrying. They are in danger.

“We can hear the engines. The isolated people are also hearing them.”
