The paper comes to analyze the Chilean constitutional tradition and its model of citizen participation, which has been built on the basis of liberal constitutional models, elaborated by the national oligarchy. Thus, the Chilean State has historically been centralized, to the detriment of the regions, localities, and civil society organizations, alienating the citizenry from State affairs and its administration. This model has made Chile, since the Social Outbreak of October 2019, enter into a profound process of constitutional changes, which seek to update to the 21st century the way in which the State relates with citizenship. This reengineering of citizen participation has its first examples through the internal organization that the Constitutional Convention gave itself, and that would seek to materialize in the New Constitution in different areas of the public space: environment, public services, decentralization, semi-direct democracy, indigenous consultation, among others.
