Political map of Europe & the Mediterranean 10 August 117 (Accession of Hadrian): Trajan set about suppressing the revolts in Mesopotamia (116–7), even crowning his own king of Parthia (Parthamaspates of Parthia) in an attempt to restore order, but fell ill and died before he could complete his efforts. He was succeeded by Hadrian, who quickly traveled to Rome to secure his authority and deal with an uprising on the Danube (Hadrian's Dacian War).
