Francisco Alves Mendes Filho was born on December 15, 1944, in the rubber plantation Porto Rico, in Xapuri, in the state of Acre. The son of a migrant from Ceará and Maria Rita Mendes, he grew up among the trails of the Amazon rainforest, learning from an early age the trade that would mark his entire life: extracting latex from native rubber trees. Even before learning to read, Chico Mendes already knew the forest like the back of his hand and understood what was at stake when someone threatened to cut it down.
Childhood and youth in the rubber plantations left little room for schooling. In most properties in the region, formal education simply did not exist, and landowners had no interest in changing that reality. It was only at the age of 19 that Chico Mendes learned to read, thanks to the communist militant Euclides Távora, who had taken part in the 1935 uprising in Fortaleza and the 1952 Bolivian Revolution. After returning to Brazil, Távora settled in Xapuri and became the young rubber tapper’s literacy teacher, opening up an entirely new world for him.
Life in the rubber plantations was marked by deeply unequal relationships. The *aviamento* system, in which rubber tappers exchanged harvested latex for industrial goods supplied by the landowners themselves, kept workers in permanent debt. Those who dared to protest faced physical punishment from foremen or were repressed by police acting on behalf of ranchers. It was in this environment of systematic exploitation that Chico Mendes shaped his political awareness and his willingness to fight.
In the 1970s, the military regime intensified conflicts in the Amazon by encouraging the replacement of rubber with cattle ranching. Land speculation advanced over areas inhabited by generations of rubber tappers and Indigenous peoples, and deforestation accelerated to make way for pastures. Faced with this scenario, Chico Mendes began his union activism in 1975, taking on the role of general secretary of the Rural Workers’ Union of Brasiléia. From the following year onward, he became actively involved in organized resistance against deforestation.
The main tool of struggle he helped develop became known as the "empate" (stand-off). The tactic involved peaceful demonstrations in which rubber tappers surrounded trees with their own bodies, preventing chainsaws and tractors from advancing into the forest. It was a form of unarmed resistance that highlighted the determination of a people willing to protect their way of life with their very existence. In 1977, Chico Mendes co-founded the Rural Workers’ Union of Xapuri and was elected city councilor for the Brazilian Democratic Movement, during which time he received his first death threats from local ranchers.
That same year, he began collaborating with the alternative Acrean newspaper *O Varadouro*, even personally distributing it in the most remote rubber plantations. In 1980, he helped found the Workers’ Party in Acre and took part in rallies alongside Luiz Inácio Lula da Silva. However, his political engagement came at a high cost: he was charged under the National Security Law as a "subversive" by ranchers who tried to smear him with false accusations. In 1984, a military tribunal in Manaus acquitted him for lack of evidence.
The year 1985 marked a turning point in Chico Mendes’ journey. In October of that year, he led the 1st National Meeting of Rubber Tappers, an event that resulted in the creation of the National Council of Rubber Tappers. The meeting also gave rise to the proposal for a "Union of the Peoples of the Forest," an unprecedented alliance between rubber tappers, Indigenous peoples, Brazil nut gatherers, fishermen, and riverside communities in defense of their territories. The idea of extractive reserves—areas where the forest could be sustainably exploited without being destroyed—gained traction and began influencing lawmakers and governments.
The alliance with the Amazon’s Indigenous peoples further strengthened the proposal and pressured the federal government to create forest reserves aimed at the non-predatory harvesting of resources like latex and Brazil nuts. The movement’s international reach grew, and between 1987 and 1988, Chico Mendes received two global recognition awards: the Global 500, awarded by the United Nations in the United Kingdom, and the Better World Society’s Environmental Medal in the United States. The rubber tapper from Acre had become a worldwide symbol of the fight for environmental preservation.
However, international recognition did not protect him from the enemies he had made over years of activism. On December 22, 1988, seven days after turning 44, Chico Mendes was shot and killed with a shotgun in the backyard of his home in Xapuri. His death provoked immediate outrage in Brazil and widespread repercussions abroad, turning the rubber tapper into a martyr for a cause that transcended borders.
Chico Mendes’ assassination did not silence the movement he helped build; on the contrary, it amplified its reach. Parks, institutes, awards, and memorials were created in his memory to preserve the message he left: that the defense of the forest and the defense of those who depend on it are, in essence, the same struggle. His legacy continues to influence generations of conservationists, activists, and lawmakers worldwide, decades after his passing.
