Polygamy: is a condition or practice or culture of having more than one spouse at the same time. It is also known as polygyny, polyandry or plural marriage. Polygamous nation: a country where polygamy is a legal culture (i.e. Nigeria, and most countries in Africa, Middle east, nay, most countries in the third world).
Polygamy on the other hand can only occur in a country where marrying more than one person is allowed, and is used to describe a marriage with multiple partners with all partners knowing of each other.
