What was the primary instrument of pope Gregory for converting German peoples Europe?

The primary instrument of Pope Gregory for converting German peoples in Europe was the Benedictine Order of monks, established by Saint Benedict in the 5th century. These monks were sent by Pope Gregory to spread Christianity among the Germanic tribes, following his vision of the "conversion of the world". Benedictine monks were often the first to arrive in newly settled areas, where they established monasteries, spread spiritual teaching and literacy, and helped to promote religious and moral values. They were also instrumental in teaching agricultural skills and introducing technological advancements to the indigenous populations. For centuries, Benedictine monks were the main missionaries in the process of converting the German peoples of Europe to Christianity.
