excubitor

The term excubitor, derived from the Latin word for "watchman" or "guard," historically referred to a select body of soldiers stationed in the imperial palace in Rome. These elite troops were responsible for the personal safety of the emperor and the security of the palace complex. The excubitors were a prominent military unit, often composed of men chosen for their loyalty, bravery, and physical prowess. Their position granted them significant influence within the empire.

Over time, the role and prominence of the excubitors evolved. They became more than just palace guards, acting as a crucial political force. Emperors sometimes relied on the excubitors to maintain order, suppress rebellions, or even to influence succession. The unit's proximity to power meant that their support could be vital for an emperor's survival and authority. This influence sometimes led to the excubitors playing a role in imperial politics, including the deposition of emperors. The excubitors eventually faded in importance as imperial power structures changed and new military units took on their responsibilities.
