The main objective is to develop understanding and knowledge about the importance of the participatory processes and their consequences with the ultimate aim of promoting active citizenship in individuals under 18 in the elections of the European Parliament. Through the U18 simulation, we will explain the functioning of the European political system and highlight the opportunities that the European Union offers to youth, as well as the importance of having the participation of young people in the objectives and strategies of the European Union. This project seeks to facilitate a more effective access to information about European parliamentary life, while promoting democratic culture and stimulating interest in the elections among people under 18.
