Proposals to create the district date back to 2010, when efforts took place until their approval in 2021. The district was officially created on July 3, 2025, through Law N° 32403, approved by the
Congress of Peru following the initiative of President
Dina Boluarte. Formerly part of
Yavari District, its capital is
Santa Rosa de Yavarí, one of three border crossings of
Tres Fronteras. The district was provisionally administered by Jack Iván Yovera Peña, provincial mayor of Mariscal Ramón Castilla, until Max Ortiz Rubio, who had been mayor of the populated centre back in 2018, was chosen as interim mayor in August. A temporary board of neighbourhood delegates was established until the election of authorities in the local elections of September 2025. Its creation and inclusion of
Santa Rosa Island led to the protest of president of Colombia
Gustavo Petro, who claimed that
Peru had usurped Colombian territory, and announced that the celebrations of the
Battle of Boyacá would be moved to nearby
Leticia in response. ==Politics==
