Tetrarchy

The Tetrarchy was a system of governance established by the Roman Emperor Diocletian around 293 AD to manage the vast Roman Empire more effectively. It divided the empire into four regions, each ruled by a leader. Diocletian appointed two main emperors, called Augusti, and each had a junior partner known as a Caesar. This arrangement aimed to ensure better local governance, improve military response, and reduce administrative challenges. While it initially brought stability, the Tetrarchy eventually struggled with power struggles and ended, leading to a return to more centralized rule in the empire.
