The rise of Geta and Caracalla to the Roman throne is a dramatic story filled with ambition, family rivalry, and political strategy. Their path to power was shaped not only by their father’s careful planning but also by the unstable environment of the Roman Empire at the end of the second century. Understanding how Geta and Caracalla became emperors requires looking at their family background, the Severan dynasty, and the system of imperial succession in ancient Rome. Their joint rule, though short-lived, reveals much about the challenges of shared power and the dangers of sibling rivalry in Roman imperial politics.
The Severan Dynasty and Family Background
Geta and Caracalla were the sons of

Caracalla’s Early Rise to Power
In 198 CE, Severus elevated Caracalla to the rank of Augustus. This move effectively made him co-emperor alongside his father. By granting this title, Severus ensured that the army and the Senate recognized Caracalla’s authority. This early promotion strengthened Caracalla’s claim to the throne and secured a smooth transition of power.
Why Was Caracalla Promoted So Early?
- To secure dynastic stability
- To prevent military rebellion
- To reinforce loyalty among Roman legions
- To establish a clear line of succession
Severus understood that Roman emperors often faced threats from rivals. By elevating Caracalla during his own reign, he minimized uncertainty.
Geta’s Path to Co-Emperorship
In 209 CE, Septimius Severus raised Geta to the rank of Augustus as well. This decision made both brothers equal co-emperors under their father. Severus likely hoped that shared power would preserve unity within the imperial family and prevent civil war after his death.
The Role of Septimius Severus in Their Succession
Septimius Severus played a decisive role in how Geta and Caracalla became emperors. Roman succession was not strictly hereditary, but Severus aimed to create a stable dynasty by promoting his sons during his lifetime.
He took both sons on military campaigns, including expeditions to Britain. By exposing them to military life, he hoped to gain the loyalty of soldiers for his heirs. In Rome, military support was essential for imperial power.
When Severus died in 211 CE in the city of Eboracum, modern-day York in Britain, both Caracalla and Geta automatically became joint emperors. His final reported advice to his sons emphasized unity and loyalty to the army.
Joint Rule After 211 CE
After their father’s death, Caracalla and Geta officially ruled together as co-emperors. However, their relationship was deeply strained. Ancient sources describe intense hostility between the brothers.
The palace reportedly became divided into two factions. Each brother surrounded himself with supporters and avoided contact with the other. There were even discussions of dividing the Roman Empire into two separate regions, one for each ruler.
Why Did Tension Increase?
- Sibling rivalry from childhood
- Competition for political influence
- Different groups of advisors
- Personal mistrust and ambition
Shared rule required cooperation, but neither brother was willing to yield authority.
The End of Geta’s Reign
The joint rule lasted less than a year. In late 211 CE, Caracalla arranged a meeting with Geta under the pretense of reconciliation. During this encounter, Geta was assassinated, reportedly in their mother Julia Domna’s presence.
After Geta’s death, Caracalla became sole emperor. He ordered a widespread purge of Geta’s supporters. Many historians estimate that thousands of people were executed for suspected loyalty to Geta.
This violent consolidation of power marked a turning point in the Severan dynasty. Caracalla’s actions demonstrated how fragile co-emperorship could be in Rome.
Political and Military Context
To fully understand how Geta and Caracalla became emperors, it is important to consider the broader political climate. The Roman Empire at this time relied heavily on military support. Emperors were often chosen or overthrown by armies.
Septimius Severus strengthened the army’s role in politics by increasing soldiers’ pay and privileges. While this ensured loyalty during his reign, it also meant that future emperors had to maintain military favor at all costs.
Caracalla continued this policy, further increasing military salaries. His dependence on the army helped secure his position after eliminating Geta.
The Importance of Dynastic Legitimacy
Roman emperors did not always pass power to their sons. Adoption, military coups, and Senate approval all played roles in succession. However, by the late second century, dynastic succession became more common.
By promoting both Geta and Caracalla as Augusti before his death, Septimius Severus attempted to normalize hereditary rule. This strategy gave the empire a sense of continuity, even though it failed to prevent internal conflict.
Legacy of Their Rise to Power
The story of how Geta and Caracalla became emperors highlights both careful planning and tragic failure. Severus successfully placed his sons on the throne, but he could not guarantee harmony between them.
Caracalla’s later reign became known for major reforms, including the Constitutio Antoniniana, which granted Roman citizenship to many free inhabitants of the empire. However, his violent seizure of sole power cast a long shadow over his rule.
Key Takeaways
- Septimius Severus prepared both sons for imperial power.
- Caracalla was promoted earlier and held senior status.
- Geta was later elevated to equal co-emperor.
- Military support was crucial for legitimacy.
- Sibling rivalry led to political violence.
Geta and Caracalla became emperors through a combination of dynastic planning, military backing, and strategic promotion by their father, Septimius Severus. Caracalla’s early elevation to Augustus secured his dominant position, while Geta’s later promotion aimed to create balance within the ruling family. However, their joint reign quickly collapsed under the weight of rivalry and ambition. The dramatic events surrounding their rise and conflict illustrate the complexity of Roman imperial succession and the constant tension between family loyalty and political survival in the ancient Roman Empire.
