The orthodox Cham have adopted a more conformist religion largely because of their close contacts with, and intermarriages with, the Malay community. In fact, the orthodox Cham have adopted Malay customs and family organization, and many speak the Malay language. They send pilgrims to Mecca, and they attend international Islamic conferences. Conflicts between the traditional and the orthodox Cham increased between 1954 and 1975. For example, the two groups polarized the population of one village, and each group eventually had its own mosque and separate religious organization.
