The article explores the concept of legal pluralism and its connection to legal realism. Legal pluralism is seen as complex and multifaceted, requiring a thorough analysis of its origins and socio-legal theories. The researchers used a functional approach to understand law and legal phenomena, finding that legal realism played a key role in shaping the idea of legal pluralism. Legal realists like K. Llewellyn believed in the existence of multiple legal systems alongside the state's law. Both legal realism and legal pluralism share a foundation in pragmatism, focusing on practical utility and understanding the functional essence of law. Llewellyn also highlighted how legal pluralism can lead to different interpretations and implementations of the same rule of law in practice.
