In many of these tasks they were assisted by the clergy. The church had suffered greatly during the days of the revolution. The church property had been confiscated. Several priests had been killed and the generation that had learned its cathechism from Voltaire and Rousseau and the other French philosophers had danced around the Altar of Reason when the Committee of Public Safety had abolished the worship of God in October of the year 1793. The priests had followed the "emigres" into their long exile. Now they returned in the wake of the allied armies and they set to work with a vengeance. Even the Jesuits came back in 1814 and resumed their former labours of educating the young. Their order had been a little too successful in its fight against the enemies of the church. It had established "provinces" in every part of the world, to teach the natives the blessings of Christianity, but soon it had developed into a regular trading company which was for ever interfering with the civil authorities. During the reign of the Marquis de Pombal, the great reforming minister of Portugal, they had been driven out of the Portuguese lands and in the year 1773 at the request of most of the Catholic powers of Europe, the order had been suppressed by Pope Clement XIV. Now they were back on the job, and preached the principles of "obedience" and "love for the legitimate dynasty" to children whose parents had hired shopwindows that they might laugh at Marie Antoinette driving to the scaffold which was to end her misery. But in the Protestant countries like Prussia, things were not a whit better. The great patriotic leaders of the year 1812, the poets and the writers who had preached a holy war upon the usurper, were now branded as dangerous "demagogues." Their houses were searched. Their letters were read. They were obliged to report to the police at regular intervals and give an account of themselves. The Prussian drill master was let loose in all his fury upon the younger generation. When a party of students celebrated the tercentenary of the Reformation with noisy but harmless festivities on the old Wartburg, the Prussian bureaucrats had visions of an imminent revolution. When a theological student, more honest than intelligent, killed a Russian government spy who was operating in Germany, the universities were placed under police-supervision and professors were jailed or dismissed without any form of trial.
