Political participation is an important mechanism of aggregation and articulation of socio-economic interests in politics, the purpose of which is the influence of citizens on political decision-making through various channels of political interaction, activities of political parties, public organizations, and movements.

The current war in Ukraine, mass protests after the announcement of the results of presidential elections in Belarus in the summer of 2020, protests against the preliminary results of parliamentary elections in Kyrgyzstan in autumn 2020, mass protests in support of the opposition in Russia in the spring of 2021 show that all post-Soviet countries to a greater or lesser degree have prerequisites for political destabilization, political change, and turmoil.

The article offered for consideration examines the impact of constitutional reforms aimed at liberalizing the political system of Kazakhstan on increasing political participation of citizens and overcoming the crisis of political participation of citizens.
