Endogamy

Endogamy refers to in group marriage, or a pattern of marriage in which the partners have a shared group affiliation. Its conceptual counterpoint is exogamy, or a pattern of marriage in which the partners are different in their group affiliation. For scholars of race and ethnic relations, the significance of endogamy stems from its relationship

From the Greek evxoZ + yapco ( “in” + “to marry”), endogamy is the marital rule according to which the spouses are selected from within the same social group (kindred, religious, ethnic, etc.). It is the opposite of exogamy. Through endogamy, social groups aim to preserve their constitutive elements (for example, power, wealth, religion, language)
