As a previous poster said, it varied according to the country. In many places the Jesuits were “suppressed” by the government, along with the whole Catholic Church. In other places they were singled out. Since they were a unified, worldwide order they were perhaps considered more dangerous than local clergy who reported to local bishops.
At one point the Church itself suppressed them, but only after they had already been banned in most places. Other countries said suppress the Jesuits, or we will suppress the Church. Individual Jesuits continued to minister in their local dioceses. It must have seemed almost miraculous, like a phoenix arising from the ashes, when the elderly remaining men again gathered as an Order.
Pray for the Jesuits.
