I believe it is illegal in India to have two wives if you are a man and you belong to the Hindu religion. (There are also Muslims in India and polygamy is legal for them). It’s unfortunate for Indian widows who live in rural parts of India because tradition typically dictates these women be shunned and excluded from religious functions after their husbands die.
In extreme cases, widows are not allowed even allowed to eat with the rest of the family. Even in cities widows are “generally expected to mourn until the end of their lives” based on the sacred texts of Manu.
