[1] One of Loncón's great-grandfathers fought the Chilean government during the invasion of Araucanía (1861–1883) and was a close ally of chief José Santos Quilapán.

[3] As a consequence land recovery activism, Loncón's maternal grandfather, Ricardo Antileo, spent time in jail during the Pinochet-era military dictatorship.

[4] In a 2017 interview, Loncón stated that the local Mapuche ceremonial centre in Lefweluan was destroyed in favour of a landfill site, and watched her brothers develop skin infections while playing in the garbage.

[6] Loncón had originally intended to study history, but was denied entry as she did not achieve the necessary score on the Prueba de Aptitud Académica.

The rector of the university Heinrich von Baer identified Loncón and other participating students and threatened to expel them if they took part of any further protests.

[4] She was part of the Ad Mapu cultural organization and the Aukiñ Wallmapu Ngulam (AWNg or Consejo de Todas las Tierras in Spanish).

[12] In 2021, Loncón was a candidate for the Chilean Constitutional Convention, running to represent the Mapuche of the Coquimbo, Valparaíso, Santiago, O'Higgins and Maule regions, and was elected.

[1] Early reports suggested Machi Francisca Linconao was seen as "the natural candidate" for indigenous members of the Constitutional Convention to support for president of the body.

However, Linconao declined to run, instead proposing that Loncón stand for the presidency of the convention during a Winter solstice meeting held in her house in Padre Las Casas.

Loncón received 96 votes in the second round, mainly from the left (Apruebo Dignidad, The List of the People) and center-left coalitions (part of Constituent Unity).

[25] Much criticism of her has been identified as part of a larger smear campaign against the Constitutional Convention by voters of the "reject" option in the 2020 Chilean national plebiscite.

[25] On July 27, 2021, the hashtag "#DestitucionDeElisaLoncon" aiming to promote an impeachment of Loncón became a trending topic in Twitter and was featured in large Chilean media outlets.

[25] Loncón has helped to build a "plurinational library" in the Constitutional Convention and bought for that purpose books by Humberto Maturana, Ximena Dávila, Frantz Fanon, Christo Brand, Linda Tuhiwai, Silvia Rivera Cusicanqui.
