Leaders are often only from one political party , social class, religion, or ethnic group Autocracy Democracy Theocracy Oligarchy

The correct answer is Autocracy.<br /><br />In an autocracy, leaders are often from one political party, social class, religion, or ethnic group. Autocracy is a system of government in which supreme power is concentrated in the hands of one person, who may be a dictator or a monarch. In such a system, the leader has absolute authority and control over the government and its institutions, and there is little or no participation or representation from other political parties, social classes, religions, or ethnic groups.<br /><br />In contrast, democracy is a system of government in which power is vested in the people, who rule either directly or through freely elected representatives. In a democracy, leaders are typically drawn from multiple political parties, social classes, religions, and ethnic groups, and there is a high degree of political participation and representation.<br /><br />Theocracy is a system of government in which a deity is recognized as the supreme civil ruler, and the deity's laws are interpreted by ecclesiastical authorities. In a theocracy, the leader is often a religious figure or a member of a specific religious group.<br /><br />Oligarchy is a system of government in which power is held by a small group of people, typically from the same social class or ethnic group. In an oligarchy, the leader is often from the same group as the ruling elite, and there is limited participation or representation from other groups.
