The period from 1735 until his death in 1746 has been nicknamed "the State Pietism", as new laws and regulations were established in favor of Pietism. Though Pietism did not last for a substantial time, numerous new small pietistic resurrections occurred over the next 200 years. In the end, Pietism was never firmly established as a lasting religious grouping.
