<p>This study delves into the rich tapestry of religious narratives surrounding local deities in India, conceptualized as myths and legends, memorates, within a folkloristic framework. It explores the multifaceted impact of local deity traditions in India at both communal and personal levels. Drawing on 28 articles identified through the PRISMA methodology and analyzed via systematic thematic analysis using the Scopus database, this research explores how the agency of local deities functions as a powerful symbol of community solidarity and cultural services, highlighting their importance on governance and individual stakeholders. It examines the interplay between Sanskritic and non-Sanskritic rituals, revealing dynamics of continuity and resistance. This paper also employs the discourse of ecology through the lens of religio-cultural institutions. The review identifies critical gaps in the literature about political mobilization, gender roles, justice, and intergenerational changes. It also points out that lack of systematic documentation poses a risk to the preservation of indigenous knowledge systems, oral histories, and localized religious practices. By calling for a broader comparative analysis across regions and cultures, this study seeks to deepen our understanding of the evolving nature of local deity worship amidst modernization.</p>
