Final answer:
Diocletian's two caesars, Galerius and Constantius, were in training to eventually become Augustus.
Step-by-step explanation:
Diocletian, to ensure stability and effective governance, implemented a unique system of governance known as the Tetrarchy. As part of this system, he appointed two caesars, Galerius and Constantius, who were intended to undergo training and preparation to eventually ascend to the position of augusti, or senior emperors.
The purpose of this arrangement was to establish a smooth transition of power and avoid the power struggles that had plagued previous successions. Galerius and Constantius were essentially heirs in training, groomed to assume the highest positions of authority in the Roman Empire.
Diocletian's decision to have caesars in training reflected his strategic vision for a more stable and secure empire. By having successors undergo a period of apprenticeship, Diocletian aimed to ensure that those who eventually assumed the role of augusti were well-prepared and knowledgeable about the challenges of ruling. This foresight was crucial in maintaining the Tetrarchy's stability and mitigating the potential for internal conflicts.
In conclusion, the concept of caesars in training, exemplified by Galerius and Constantius, was a key element of Diocletian's innovative governance model. It aimed at fostering a seamless transition of power and fortifying the Roman Empire against the internal discord that had previously weakened its leadership.
