This refers to the practice of polyandry, a form of marriage where one woman is married to two or more men.
Polyandry has been practiced in various cultures throughout history, often due to factors such as resource scarcity, female infanticide, or a desire to maintain family property within a lineage. One well-known example of polyandry is the fraternal polyandry practiced in some parts of Tibet, where brothers share a single wife to preserve their family’s land and resources.
