Legal anthropology, also known as the anthropology of laws, is a sub-discipline of anthropology that uses an interdisciplinary approach to "the cross-cultural study of social ordering". The questions that Legal Anthropologists seek to answer concern how is law present in cultures? How does it manifest? How may anthropologists contribute to understandings of law?

Earlier legal anthropological research focused more narrowly on conflict management, crime, sanctions, or formal regulation. Bronisław Malinowski's 1926 work, Crime and Custom in Savage Society, explored law, order, crime, and punishment among the Trobriand Islanders. The English lawyer Sir Henry Maine is often credited with founding the study of Legal Anthropology through his book Ancient Law (1861). An ethno-centric evolutionary perspective was pre-eminent in early Anthropological discourse on law, evident through terms applied such as ‘pre-law’ or ‘proto-law’ in describing indigenous cultures. However, though Maine’s evolutionary framework has been largely rejected within the discipline, the questions he raised have shaped the subsequent discourse of the study. Moreover, the 1926 publication of Crime and Custom in Savage Society by Malinowski based upon his time with the Trobriand Islanders, further helped establish the discipline of legal anthropology. Through emphasizing the order present in acephalous societies, Malinowski proposed the cross-cultural examining of law through its established functions as opposed to a discrete entity. This has led to multiple researchers and ethnographies examining such aspects as order, dispute, conflict management, crime, sanctions, or formal regulation, in addition (and often antagonistically) to law-centred studies, with small-societal studies leading to insightful self-reflections and better understanding of the founding concept of law.

Contemporary research in legal anthropology has sought to apply its framework to issues at the intersections of law and culture, including human rights, legal pluralism, Islamophobia and political uprisings.

Legal Anthropology provides a definition of law which differs from that found within modern legal systems. Hoebel (1954) offered the following definition of law: "A social norm is legal if its neglect or infraction is regularly met, in threat or in fact, by the application of physical force by an individual or group possessing the socially recognized privilege of so acting."

Maine argued that human societies passing through three basic stages of legal development, from a group presided over by a senior agnate, through stages of territorial development and culminating in an elite forming normative laws of society, stating that "what the juristical oligarchy now claims is to monopolize the knowledge of the laws, to have the exclusive possession of the principles by which quarrels are decided."

This evolutionary approach, as has been stated, was subsequently replaced within the anthropological discourse by the need to examine the manifestations of law's societal function. As according to Hoebel, law has four functions:

1) to identify socially acceptable lines of behaviour for inclusion in the culture. 2) To allocate authority and who may legitimately apply force. 3) To settle trouble cases. 4) To redefine relationships as the concepts of life change.

Legal theorist H. L. A. Hart, however, stated that law is a body of rules, and is a union of two sets of rules:
