Elizabeth hated Frederick the Great of Prussia. She claimed that "The King of Prussia is certainly a bad prince who has no fear of God before his eyes; he turns holy things into ridicule, and he never goes to church." The real reason was that Frederick had expressed his opinion about Elizabeth's private life, and she was not the woman to forgive his remarks. Then again, Frederick had an excellent army of 200,000 men; Elizabeth's chancellor, on that account, called Prussia "the most dangerous of neighbors, whose power it was necessary to break." Russia, Austria, France, and Saxony, entered into a secret alliance against Prussia. Frederick found it out, and in 1756, began the famous Seven Years' War. The same year, 83,000 Russians under Apraxine crossed the frontier and seized East Prussia. A battle was fought; the Russians were the victors, but Apraxine fell back across the Niemen. France and Austria suspected treachery; Apraxine was arrested and the chancellor was dismissed and exiled. Fermor was appointed (p. 181) commander-in-chief. The Russian army recrossed the frontier in 1758, took Koenigsberg and bombarded Kuestrin on the Oder. Frederick with 32,000 men attacked the Russian army 89,000 strong at Zorndorf. The Russians fought stubbornly but were defeated with a loss of 20,000 men. Fermor was recalled, and succeeded by Soltykof who, in 1759, entered Frankfort on the Oder. Another battle was fought and Frederick was defeated by greatly superior numbers. He lost 8,000 men. Prussia was exhausted, but his enemies, too, began to feel the expense of the war. Elizabeth, however, was determined to humble the outspoken King when she died suddenly in 1761. She was succeeded by her nephew Peter Feodorovitch under the name of Peter III. Elizabeth, although careless in her mode of living, was a stout supporter of the Greek Church. In 1742, she agreed with the Holy Synod to suppress all other churches, as well as the Mosques or Mahomedan temples in the south. This caused a revolt of the Mahomedans. The Jews were also expelled in some parts of the empire. A fever of fanaticism broke out; fifty-three _raskolnik_ in Russia, and one hundred and seventy-two in Siberia, burned themselves to death. Count Ivan Schouvalof, one of Elizabeth's friends, believed in education and was given a free hand. He ordered that the priests and their children should attend school, on penalty of being whipped. He founded the University of Moscow, which has educated many learned Russians. To induce students to enter, he induced Elizabeth to (p. 182) make a law that all students should be tchins of the tenth grade, and the professors hold the eighth grade. He sent young men abroad to study and established higher schools in every Government. Schouvalof was also the founder of the Academy of Fine Arts at St. Petersburg.
