Coverture laws were legal doctrines that subsumed a married woman's legal identity under that of her husband, effectively stripping her of independent legal rights. This meant that upon marriage, women could not own property, enter contracts, or engage in legal actions without their husband's consent. These laws reinforced the patriarchal structure of society and were significant in the context of women's rights and suffrage movements, as they highlighted the need for legal reforms to empower women and ensure their rights as individuals.
