This chapter deals with five categories of nonstate entities that have been significant actors in the Latin American subsystem: the Roman Catholic Church, multinational business enterprise, international labor organizations, guerrilla insurgency groups, and transnational political parties. The nature of the Roman Catholic Church as an actor in the modern international political system is unique. Church divisiveness over current social issues is instructive with regard to its policy-making procedures and revealing of the decentralized nature of the church as a transnational actor. A multinational corporation is a group entity with a legal personality; while corporate control remains centered within some sovereign state, the corporation exhibits a great deal of independence as an actor in the international political system. Toward the end of the nineteenth century, international business actors who were to enjoy many years of large-scale activity in Latin America began to appear.
