The culture of the Marshall Islands forms part of the wider culture of Micronesia. It is marked by pre-Western contact and the impact of that contact on its people afterward. The Marshall Islands were relatively isolated. Inhabitants developed skilled navigators, able to navigate by the currents to other atolls. Prior to close contact with Westerners, children went naked and men and women were topless, wearing only skirts made of mats of native materials. Land was and remains the most important measure of a family's wealth. Land is inherited through the maternal line.
