Caracalla's campaigns of 214–216 AD were a string of successful military campaigns led by Roman emperor Caracalla against Parthian client states in Upper Mesopotamia, of which the kingdoms of Adiabene and of Osroene.
Without choosing a successor himself, his two sons, Caracalla and Geta, took power. To avoid hostilities between the two new joint emperors, they decided to divide the empire in half and set the border at the Bosphorus.[5]
On 26 December 211, at a reconciliation meeting arranged by their mother, Geta was assassinated by members of the Praetorian Guard loyal to the 23-year-old Caracalla. Geta died in his mother's arms. It is widely accepted, and clearly most likely, that Caracalla ordered the assassination himself, as the two had never been on favourable terms with one another, even after having split the empire, and much less after succeeding their father.[4]
Caracalla then persecuted and executed most of Geta's supporters and ordered a damnatio memoriae pronounced by the Senate against his brother's memory.[6][7] Geta's image was removed from all paintings, coins were melted down, statues were destroyed, his name was struck from papyrus records, and it became a capital offence to speak or write Geta's name.[8] In the aftermath of the damnatio memoriae, an estimated 20,000 people were massacred.[7][8] Those killed were Geta's inner circle of guards and advisers, friends, and other military staff under his employ.[8]
Prelude
The Roman Empire during the reign of Caracalla.
In spring 214, Caracalla departed for the eastern provinces, travelling through the Danubian provinces and the Anatolian provinces of Asia and Bithynia.[9] He spent the winter of 214/215 in Nicomedia. By 4 April 215 he had left Nicomedia, and in the summer he was in Antioch on the Orontes.[9] By December 215 he was in Alexandria in the Nile Delta, where he stayed until March or April 216,[9] preparing for a campaign against Parthia and its client states.[10]
According to Roman historian Cassius Dio, Caracalla took Arbela in 216 AD, and searched all the graves there, wishing to ascertain whether the Arsacid kings were buried there.[20][21] Many of the ancient royal tombs were destroyed.[19]
