🏛️§ Caracalla and Geta.

Caracalla
Birth name: Lucius Septimius Bassianus
He later became known as Marcus Aurelius Antoninus. "Caracalla" was originally a nickname related to a cloak he wore.

Mother: Julia Domna
Brother: Geta.
Wife: Fulvia Plautilla.
It was a political marriage arranged when Caracalla was approximately 14 years old. They had a daughter, although the sources do not clearly preserve her name. The marriage ended after the downfall of Plautilla's father, Plautianus. Plautilla was exiled and later executed.
Children:
Yes, a daughter with Fulvia Plautilla.

What territories did Caracalla conquer?
Here too we must be careful with the word "conquered". Caracalla carried out several military campaigns, but not all of them resulted in permanent conquests.
Britain, 208-211 AD
He participated alongside his father in campaigns against the peoples of northern Britain, especially in present-day Scotland. These operations achieved some successes and temporarily strengthened the Roman frontier, although Rome did not manage to permanently conquer all of Caledonia.
Germania, 213 AD
Caracalla led a campaign against the Alamanni in the regions of Raetia and Germania Superior. The campaign allowed him to gain military prestige and strengthen the Roman borders.
The Orient and Parthia, 216-217 AD
He attempted to launch a major campaign against the Parthian Empire, but died before achieving a decisive conquest. Therefore, it cannot be said that Caracalla conquered Parthia.

Also:
He strengthened his relationship with the Roman army.
He personally participated in military campaigns.
He reinforced the western borders of the Empire.
He continued his father's military policies.
He carried out important architectural projects, including the famous Baths of Caracalla in Rome.
He attempted to expand Roman influence in the East through his campaigns against Parthia.

Caracalla's main achievements
The most important was the Constitutio Antoniniana of 212 AD, through which he granted Roman citizenship to virtually all free inhabitants of the Empire. It was one of the most significant legal measures of his reign and also allowed for an increase in state tax revenues.

Personality:
Very ambitious.
Militaristic.
Authoritarian: preferred to impose his will rather than convince through arguments.
Irascible.
Especially distrustful of Getafe.
Proud and arrogant.
Severe and harsh.
Generous with the army.
Cruel according to sources.

Geta
Full name: Publius Septimius Geta
Birth: March 7, 189 AD
Father: Septimius Severus
Mother: Julia Domna
Brother: Caracalla, born approximately 11 months earlier.
Encyclopedia of World History

Children: No children of Geta are known.
Years in government:
He was named Caesar in 198 AD
He was named Augustus in 209 AD
He ruled as co-emperor alongside Caracalla from February to December 211 AD
What territories did he conquer?
Here an important clarification must be made: Geta did not make any major territorial conquests on his own.
During the British campaign of 208–211 AD, his father took Geta and Caracalla with him to gain experience in government. While Septimius Severus and Caracalla directed military operations to the north, Geta was primarily involved with the civil administration of Britain south of Hadrian's Wall.
The campaigns were mainly led by Septimius Severus and Caracalla, although Geta was part of the imperial family that participated in the campaign.
Personal achievements:
He gained administrative experience in Britain.
He was prepared by his father to participate in the imperial government.
He shared the title of Augustus with Caracalla.
It represented a possible alternative to the government of Caracalla, something that ended up causing a very serious political rivalry.
