This study seeks to analyze the theoretical and methodological foundations of Anthropology, focusing on its historical development and its interrelationship with other human sciences, especially with the Anthropology of Comparative Law. The article examines the legal phenomenon in distinct cultures, seeking to understand how different societies organize, interpret and apply Law. This study is not limited to analyzing legal norms, but also investigates the impact of norms on social practices, cultural relations, and conceptions of justice in each context within the systematics of Comparative Law. The objective is to analyze how this discipline understands the human being in its entirety, addressing cultural, biological, and social aspects. The methodology used is qualitative and is based on the bibliographic review of works by classical and contemporary authors, such as Immanuel Kant, Franz Boas, and Louis Assier-Andrieu. This approach allows a broad view of the different areas of Anthropology, including Archaeological, Biological, Linguistic and Cultural Anthropology, in addition to highlighting the interconnection with Comparative Law. Furthermore, the premises for an anthropology of Comparative Law allow for the understanding of Law as a dynamic element of society.
