This research, set in a Latin American context, aimed to delve into the political participation of ethnic minorities, particularly indigenous peoples, and its relationship with democracy, political systems, and parties. Using a comprehensive review of literature from various databases including Scopus, Web of Sciences, Wiley, and EBSCO, and employing the PRISMA method, it sought to understand the political perceptions and preferences of these minorities within society. The study underscored the critical role of ethnic minority participation, especially of indigenous peoples, in guaranteeing representation in the democratic framework. Notable differences emerged in how these minorities view democracy compared to the broader populace. Recognizing ethnic minorities in political roles not only acknowledges their unique challenges but also aids their integration into the political fabric. The overarching conclusion emphasized the indispensable nature of their participation for a just and genuinely democratic society, highlighting the significance of indigenous perspectives on democracy and the pressing need to respect their cultural norms. Political parties also play a pivotal role in influencing perceptions about ethnic diversity. What sets this study apart is its holistic examination of the political engagement of ethnic minorities, shedding light on their views and preferences in relation to democracy and the wider political system, and stressing the role of political parties in fostering a more inclusive political landscape.
