Trousers or pants (American English) first appear in recorded history among nomadic steppe-people in Western Europe. Archaeological evidence suggests that men and women alike wore trousers in that cultural context. However, for much of modern history, the use of trousers has been restricted to men. In many regions, this norm was enforced not only by social custom but also by law. There are, however, many historical cases of women wearing trousers in defiance of these norms, for a variety of reasons, including comfort, freedom of movement, fashion, disguise, attempts to evade the gender pay gap, and attempts to establish an empowered public identity for women. Especially in the 20th and 21st centuries, the customs and laws restricting this manner of dress have relaxed dramatically, reflecting a growing acceptance and normalisation of the practice.
