A theocracy is a system of governance where religious leaders or institutions hold political power, and legal systems are based on religious laws. In a theocracy, the state's legitimacy is derived from divine authority, and religious doctrine directly influences political decisions. This form of government often limits pluralism and the separation of church and state, as laws may reflect the beliefs of a particular faith. Theocratic systems can vary in their implementation, ranging from democratically elected leaders who uphold religious tenets to absolute rulers who wield power under the guise of religious mandate.
