The emperor Trajan died later in the year and was succeeded by Hadrian and the rebellion in Judea was finally crushed by Quietus. Quietus was murdered later in the year (AD 118) and it has been theorized that Quietus was assassinated on the orders of the new emperor, Hadrian, for fear of Quietus' popular standing with the army and his close connections to Trajan.
