What term refers to the practice of marrying within one’s own tribe or group?

The term that refers to the practice of marrying within one’s own tribe or group is endogamy. This practice is often observed in various cultures, where marriage partners are selected from specific social, ethnic, or cultural groups, thereby reinforcing social ties and cultural identity within that group. Endogamy can serve to maintain cultural traditions, strengthen community bonds, and ensure that resources remain within the network of the group.

The concept of endogamy is important in understanding social structures and cultural practices related to marriage, as it highlights how family and kinship networks are preserved and propagated within specific cultural or social boundaries.
