Leo called Theodore Lascaris to Rome to give instruction in Greek, and established a Greek printing-press from which the first Greek book printed at Rome appeared in 1515.
In 1742, after the extinction of the two senior lines of this family, the Sulzbach branch became the senior line, and its head, the elector Charles Theodore, inherited Bavaria in 1777.
It remained the capital of the Palatinate for nearly sixty years, being especially flourishing under the elector Charles Theodore.
He purchased the allegiance of the stryeltsi, or musketeers, and then, summoning the boyars of the council, earnestly represented to them that Theodore, scarce able to live, was surely unable to reign, and urged the substitution of little Peter.
But the reactionary boyars, among whom were the near kinsmen of Theodore, proclaimed him tsar and Matvyeev was banished to Pustozersk, in northern Russia, where he remained till Theodore's death (April 27, 1682).
