Final answer:
Polygamy is the practice of marriages involving more than one partner, such as among members of the Fundamentalist Church of Jesus Christ of Latter-Day Saints (FLDS), a Mormon denomination.
Step-by-step explanation:
The practice of marriages involving more than one partner is known as polygamy. One example of polygamy is found among members of the Fundamentalist Church of Jesus Christ of Latter-Day Saints (FLDS), a Mormon denomination.
Polygamy is the socially sanctioned union of more than two adults at the same time. In polygamous societies, families usually begin with a two-person marriage between a man and a woman. Adding partners is frequently a sign of status and is considered an ideal for families in polygamous societies.
It is important to note that the larger Mormon Church officially renounced polygamy in 1890, but some fundamentalist Mormon sects, like the FLDS, still practice it.
