Religious syncretism and cultural adaptation are significant themes in African diasporas across continents, with Ethiopia's diaspora providing a unique case study due to its complex history and diverse religious practices. The study employs a structured questionnaire designed for online distribution across various diaspora communities. Data collection was conducted via an electronic platform with a total sample size of 500 respondents from different regions of Ethiopia, including urban and rural settings. A notable finding is the significant overlap (42%) between traditional Ethiopian religious practices and Christianity among diaspora members, indicating a complex interplay of cultural elements in their daily lives. The research underscores the dynamic nature of cultural adaptation within diaspora communities. It provides insights into how religious syncretism shapes identity and community cohesion. Future studies should consider longitudinal data collection to track changes over time, as well as qualitative methods for deeper understanding of individual experiences.
