简史：17 世纪晚期，西班牙传教士来到关岛，当时岛上只居住着土著查莫罗人，他们是马来-波利尼西亚人后裔。查莫罗人目前占人口的比例略多于三分之一，在岛屿政治和社会生活中发挥着积极作用。
Brief history: The island was inhabited by the indigenous Chamorro people of Malayo-Polynesian descent when missionaries from Spain arrived in Guam in the late seventeenth century. The Chamorro now constitute just over one third of the population and play an active role in the political and social life of the island.
