John Foxe: "Acts and Monuments," 1503 (4.30ff)

The history of the Turks continues with Orchan, Mahomet (died 1419?), and Amurath, the sixth, seventh, and eighth Mahometan Emperors (30-34). Greece, Thracia, Croatia, Asia and southern Europe are troubled and beseiged. The Turks set up their seats at Adrianople. Whomever and wherever the Turks conquered, people were instructed in Turkish religion, law and customs—hostile take-overs. Belgrade, Hungary is seiged for a while. Johanne Hunniades arises as a Christian warrior who stops the lusty Turks.
