Uruguay missions saved In 1750 the Treaty of Madrid between Spain and Portugal transferred to Portugal the territory of the seven missions on the Uruguay River, and the Guaranis were ordered to leave; they refused, being familiar with the Portuguese as slave hunters. Seven years of guerrilla warfare killed thousands of them (see Guarani War). The Jesuits secured a royal decree restoring the disputed mission territory to Spanish jurisdiction. Two missions in 1747 and a third in 1760 were established in the sub-tribe of the Itatínes, or Tobatines, in central Paraguay, far north of the older mission group. In one of these, (founded 1747), Martin Dobrizhoffer ministered for eight years.
