[3] After massive protests and riots sparked in October 2019, an agreement was reached on 15 November 2019 between several political parties to start the process to write a new Constitution.

[4] In case the first referendum was approved (originally scheduled for 26 April 2021), a special election would be called to select the members of the Constitutional Convention.

However, due to the impact of the COVID-19 pandemic in Chile, the first referendum was moved to 25 October and the eventual election of the members of the Convention was scheduled for 11 April 2021.

Also, different mechanisms in the inscription of candidates and the election system itself were designed to ensure gender parity in the Convention, being the first assembly of this kind in the world with equal representation of men and women.

[7] The election's results were considered a surprise and a complete rearrangement of the political system in Chile established since the end of Pinochet's dictatorship in 1990.

Although Chile Vamos, the governing alliance, was the most voted list in the country, it represented the lowest results in Chilean modern history for right-wing politics, not even reaching the third of members needed to veto in the Convention.

Citizens identifying as indigenous could choose one of the ballots: the beige for the at-large election or the green for the reserved seats (with different candidates depending on its group).

Other proposals to allow more diversity in the Constituent Assembly were rejected, including one to secure 5% of the candidacies to people from gender or sexual minorities or to establish 3 electoral districts (with 8 seats) for Chileans living abroad.
