Antauro Igor Humala Tasso (born 29 June 1963) is a Peruvian ethnocacerist, a former army major, and nationalist leader.

He and his brother Ollanta Humala had previously led 50 followers in the brief Locumba uprising against President Alberto Fujimori during the dying days of his regime in October 2000.

[3] Assisted by a large group of followers (press reports range from 70 to 300 in their estimates), demanded the resignation of President Alejandro Toledo, whom he accused of selling Peru out to foreign (particularly Chilean) investors.

[7] In the recent 2021 president election, Humala entered into an alliance with the candidate for Free Peru (Perú Libre), Pedro Castillo.

[8] The alliance is conditioned on an early pardon from his prison sentence and his reinstatement into the military, potentially leading the armed forces.

In return, he pledged to support Castillo and defend him from a potential military coup led by conservative generals with ties to the far right including former presidential candidate, Rafael López Aliaga.

[9][10] In 2006, Antauro Humala published his book Etnonacionalismo: Izquierda y Globalidad (Visión Etnocacerista) in which he laid out the anticolonial and Neo-Incan ideology of his Etnocacerist movement.

In February 2015, a report from the Directorate of Criminalistics of the National Police of Peru on the bodies of the four law enforcement officers who died in this coup, indicates that the bullets that caused their death came from above and behind, while Antauro Humala's group was ahead of them.

The argument that there are witnesses claiming that the deaths were caused by military snipers from the government of Alejandro Toledo turns out to be contradictory, because it was supposedly an assault.
