Conrad Bussow was a German mercenary from Lower Saxony who lived in Riga in the 1590s and in Muscovy in 1600–1611. In 1614–1617 Bussow compiled The Disturbed State of the Russian Realm, an eye-witness history of the Time of Troubles. An early manuscript of his book was plagiarized by Peter Petreius in his History of the Grand Duchy of Muscovy.
