This chapter from "Invitation to Law & Society" explores the complex relationship between societal structures and legal systems, arguing that law is not a transcendent, universal concept, but rather a social product that evolves in tandem with economic and cultural conditions. It examines how thinkers like Max Weber, Henry Maine, and Émile Durkheim theorized the co-evolution of law and society, highlighting the shift from traditional to rational law and from status-based to contract-based legal frameworks. The text also scrutinizes how economic forces shape legal systems and the legal profession, with Karl Marx's materialist perspective influencing analyses of issues like the criminalization of poverty. Finally, it addresses the culture of control in modern societies, discussing the rise of surveillance and mass incarceration, and challenges conventional definitions of law by exploring both formal and informal mechanisms of social control across diverse communities.
