The pursuit of sustainable peace and development in Africa faces numerous challenges, including persistent conflicts, economic instability, and social fragmentation even though sustainable peace is a panacea for growth and advancement. This paper explores the transformative potential of Igwebuike, an indigenous Igbo-African philosophy, as a framework for addressing these challenges. Igwebuike, meaning “there is strength in unity,” emphasizes communal harmony, collective strength, and mutual support. By analyzing its philosophical foundations and practical applications, this study illustrates how Igwebuike can enhance conflict resolution, promote inclusive development, and strengthen social cohesion. Case studies from different African contexts were employed to demonstrate the successful integration of Igwebuike principles in fostering community-driven initiatives and sustainable resource management. Despite modern challenges such as increasing individualism and cultural shifts, Igwebuike offers a culturally resonant approach to peace-building and development. This paper argues that embracing Igwebuike can provide African nations with innovative and effective strategies for achieving long-term stability and prosperity for all. The descriptive and analytic methods were utilized to sustain this research; recommendations were made and the researcher held by way of conclusion that the principles of Igwebuike can enhance conflict resolution, promote sustainable development, and strengthen social welfare systems, paving the way for a more harmonious and prosperous future for the continent
