Devolutionary forces are the political, social, or economic factors that lead to the decentralization of power from a central government to regional or local governments. These forces can arise from demands for greater autonomy by specific regions or groups, and they often reflect ethnic, cultural, or historical identities that challenge the authority of a central state. Understanding devolutionary forces helps to explain how and why certain regions seek independence or greater self-governance, as well as the challenges these movements pose to national unity.
