text: He tolerated all faiths in his realm, but Protestantism remained the favoured religion, and Catholics were not chosen for higher state positions. Frederick wanted development throughout the country, adapted to the needs of each region. He was interested in attracting a diversity of skills, whether from Jesuit teachers, Huguenot citizens, or Jewish merchants and bankers. Frederick retained Jesuits as teachers in Silesia, Warmia, and the Netze District, recognising their educational activities as an asset for the nation. He continued to support them after their suppression by Pope Clement XIV. He befriended the Roman Catholic Prince-Bishop of Warmia, Ignacy Krasicki, whom he asked to consecrate St. Hedwig's Cathedral in 1773. He accepted countless Protestant weavers from Bohemia, who were fleeing from the devoutly Catholic rule of Maria Theresa, granting them freedom from taxes and military service. Constantly looking for new colonists, he encouraged immigration by repeatedly emphasising that nationality and religion were of no concern to him. This policy allowed Prussia's population to recover very quickly from its considerable losses during Frederick's three wars.
  Though Frederick was known to be more tolerant of Jews and Roman Catholics than many neighbouring German states, his practical-minded tolerance was not fully unprejudiced. Frederick wrote in his :
  We have too many Jews in the towns. They are needed on the Polish border because in these areas Hebrews alone perform trade. As soon as you get away from the frontier, the Jews become a disadvantage, they form cliques, they deal in contraband and get up to all manner of rascally tricks which are detrimental to Christian burghers and merchants. I have never persecuted anyone from this or any other sect; I think, however, it would be prudent to pay attention, so that their numbers do not increase.
