Step-by-step explanation:
The subject of this question is History.
The era of the 5 Good Emperors, which lasted from 96 to 161 CE, is known for a period of stability and competent leadership in the Roman Empire. This period is often referred to as the Pax Romana and was characterized by emperors who successfully managed the empire at its height.
During this time, emperors appointed their own successors based on merit, rather than passing the power to their family members. The Roman Empire prospered under this relatively meritocratic system of political succession, with the empire achieving its greatest territorial expansion under the rule of Emperor Trajan.
