What is Polygamy?

Polygamy refers to the practice of maintaining multiple spouses at the same time.

In Greek, ‘poly’ means ‘more than one’; thus, polygamy is a generic term used to indicate a marriage with multiple partners.

These multiple partners within a polygamous marriage are completely aware of each other’s existence and specific roles.

Although polygamy is illegal in many countries worldwide, certain religious and cultural prescriptions sanction the practice of polygamy.

Muslims are religiously permitted to practice polygamy. There is a single household in a polygamous marriage, where all the partners live together.

Polygamous marriages can be of two types- polyandry and polygyny. The practice is known as polyandry when a man is married to more than one woman.

While if a woman is married to more than one man, the practice is known as polygyny. Polyandry can be further subdivided into fraternal and non-fraternal categories.

Polygyny can be either the sororal or non-sororal variants.

What is Bigamy?

Bigamy is the practice of marrying an individual when one is still legally married to another individual. It is used as a legal term to connote a criminal offence.

The word ‘bigamy’ has also originated from Greek, where ‘bi’ means two.

Thus, bigamy is entering into a marriage contract for the second time without legally severing the initial marriage contract with a legally sanctioned divorce.

From a legal standpoint, the second marriage will be considered invalid. In a bigamous martial alliance, the two partners involved do not know each other’s existence.

Moreover, two separate households are maintained by a bigamist to continue concealing this alliance.

Although bigamy is allowed in a few nations worldwide, it is illegal in almost all societies.

Moreover, polygamy does not have the same religious and cultural backing. It is a term invoked in a court of law.
