domesticus

The origins of the word domesticus can be traced to the late 3rd century of the Late Roman army. They often held high ranks in various fields, whether it was the servants of a noble house on the civilian side, or a high-ranking military position. After serving under the emperor for a certain duration, the Domestici would be able to become leaders themselves and potentially command their own regiment of legionaries in the military. Relatively, the most important offices were the “Comes Domesticorum” also known as, “Commander of the Protectores Domestici,” and “Comes rei Militaris” or General.
