Samuel Fritz
Between 1686 and 1715, he founded thirty-eight missions along the length of the Amazon River, in the country between the Rio Napo and Rio Negro, that were called the Omagua Missions. The most important of these were Nuestra Señora de las Nieves de Yurimaguas, and San Joaquín de Omaguas, which was founded in the first years of Fritz’s missionary activities and then moved in January 1695 to the mouth of the Ampiyacu river, near the modern-day town of Pebas in the Peruvian Department of Loreto. These missions were continually attacked by the Brazilian Bandeirantes beginning in the 1690s.
