The research seeks to collaborate to advance the debate on the intertwining between Ancestry, History, and Environmental Education. It analyzes the pedagogical experience developed by the authors in the project "Young Environmental Guardians from Riverside Communities", which takes place in the Brazilian Amazon. The project's purpose is to reinforce the youth's commitment to the Amazon and the riverside territories, reaffirming the principles of the defense of life, "buen vivir," and socio-environmental justice. The article narrates the project's meetings, their objective and subjective aspects, in conjunction with a critical view of the History of the Amazon. It is argued that the recognition of Ancestry can pedagogically contribute to reestablishing the links of collectivity towards a more equal society and healthy environment.
