The missions were mismanaged and abandoned by the Guaraní. Today, these ruins of a 160-year experiment have become a tourist attraction. Tomé de Sousa, first Governor General of Brazil, brought the first group of Jesuits to the colony. The Jesuits were officially supported by the King, who instructed Tomé de Sousa to give them all the support needed to Christianize the indigenous peoples. The first Jesuits, guided by Manuel da Nóbrega, Juan de Azpilcueta Navarro, Leonardo Nunes, and later José de Anchieta, established the first Jesuit missions in Salvador and in São Paulo dos Campos de Piratininga, the settlement that gave rise to the city of São Paulo. Nóbrega and Anchieta were instrumental in the defeat of the French colonists of France Antarctique by managing to pacify the Tamoio natives, who had previously fought the Portuguese. The Jesuits took part in the foundation of the city of Rio de Janeiro in 1565. The success of the Jesuits in converting the indigenous peoples is linked to their efforts to understand the native cultures, especially their languages. The first grammar of the Tupi language was compiled by José de Anchieta and printed in Coimbra in 1595. The Jesuits often gathered the aborigines in communities (the Jesuit Reductions) where the natives worked for the community and were evangelised. The Jesuits had frequent disputes with other colonists who wanted to enslave the natives. The action of the Jesuits saved many natives from being enslaved by Europeans, but also disturbed their ancestral way of life and inadvertently helped spread infectious diseases against which the aborigines had no natural defenses. Slave labor and trade were essential for the economy of Brazil and other American colonies, and the Jesuits usually did not object to the enslavement of African peoples, but rather critiqued the conditions of slavery. The Suppression of the Jesuits in Portugal, France, the Two Sicilies, Parma, and the Spanish Empire by 1767 was deeply troubling to Pope Clement XIII, the society's defender. On 21 July 1773 his successor, Pope Clement XIV, issued the papal brief "Dominus ac Redemptor," decreeing:    The suppression was carried out in all countries except Prussia and Russia, where Catherine the Great had forbidden its promulgation. Because millions of Catholics (including many Jesuits) lived in the Polish provinces recently annexed by the Kingdom of Prussia, the society was able to maintain its continuity and carry on its work all through the period of suppression.
