Corporate governance—the systems, principles, and processes by which corporations are directed and controlled—has evolved over centuries from rudimentary practices in early commerce to multifaceted frameworks that underpin modern business ethics and transparency. This research paper traces the historical origins of corporate governance, beginning with early mechanisms of oversight in merchant guilds and state-sponsored enterprises, through the industrial revolution and the emergence of formally structured boards, to post-Enron regulatory reforms in the twenty-first century. Incorporating insights from seminal theories such as agency theory (Jensen & Meckling, 1976), stewardship theory (Donaldson & Davis, 1991), and stakeholder theory (Freeman, 1984), the paper reviews empirical studies and conceptual models that inform today’s understanding of corporate governance. In addition, the work examines how governance is measured through indices, scorecards, and multi-dimensional frameworks; identifies key determinants including regulatory, cultural, and economic factors; and highlights unresolved questions that provide compelling directions for future research. This review endeavors to synthesize the extant literature in order to provide scholars and practitioners with a panoramic view of how corporate governance has developed, the major contributions that have shaped its study, and prospects for future inquiry.
