Emperor Septimius Severus died in Eboracum, modern-day York, while planning a military campaign against the Caledonians, a people from present-day Scotland known for their fierce resistance to Roman control. His death on February 4, 211, not only marked the end of a significant reign, but it also triggered a power struggle between his two sons, Caracalla and Geta. Severus had attempted to consolidate power by grooming both sons to work together, urging them to maintain peace as they co-ruled. However, their differing personalities and aspirations led to open conflict following their father's demise.

Caracalla, the elder brother, was known for his strong military backing and aggressive policies, while Geta, the younger, was seen as more diplomatic but lacked the same support base. The immediate aftermath of their father's death saw the brothers trying to assert their dominance and control over the Roman Empire, which began to unravel under their rivalry. Caracalla soon took steps to eliminate Geta, entrenching himself further as the sole ruler, a process which culminated in the assassination of Geta later in 211. This brutal conflict set a precedent for future imperial power struggles within Rome and ultimately contributed to the empire's instability during the 3rd century.
