This chapter explores the political function of the British coronation as distinct from, yet interconnected with, its theological and legal dimensions. The chapter examines seven core elements of the coronation—acclamation, oath, anointing, investiture, crowning, enthroning, and homage—highlighting their varied constitutional roles. Specifically, these elements underscore the Sovereign’s relationship to the state and the people, manifesting both a historic continuity and adaptability in symbolism and public affirmation of authority. The chapter also traces the evolution of coronation practices from feudal and imperial roots, influenced by European traditions and Roman law, and how these rituals support and reflect the Sovereign’s status as head of state. By reaffirming legitimacy through homage and acclamation, the coronation not only reflects continuity in the monarchical structure but also adapts to contemporary contexts, as seen in recent adjustments to ritual language. Moreover, the coronation aids in consolidating the state’s authority, linking symbolic customs to the stability and legitimacy of the monarchy. This chapter thus provides a detailed understanding of how the coronation functions politically to embody and sustain the unity, authority, and legacy of the British monarchy.
