Maximinus Thrax was Roman emperor from 235 to 238 CE. Troops raised him after killing Severus Alexander. His frontier wars were costly. De Imperatoribus Romanis: Maximinus Thrax
He faced a revolt backed by the Senate. His own soldiers then killed him outside Aquileia.
His accession is a common starting point for the Third Century Crisis. It did not cause every later problem. But it exposed the army's power to choose a ruler. The Eastern Roman Empire overview places that change in the longer imperial history.
TL;DR: Maximinus rose from a long army career rather than the old senatorial elite. He spent his reign on campaign and needed heavy revenue to support it. A revolt in Africa won Senate backing. Even after the first rebels died, the Senate chose new emperors against him. His march into Italy stalled at Aquileia, where hunger and failure turned his troops against him.

What is known about his early life?
Maximinus came from Thrace, a region in the Balkans. His later nickname Thrax means the Thracian. It is not proof that every story about his parents, language or education is true. The evidence for his early life is thin. De Imperatoribus Romanis
Stories made him a shepherd of humble origin. They also made him unusually large and strong. Some of that image may reflect a physically imposing soldier. Much of it became a way for elite writers to present him as crude and foreign.
His Roman names do not establish a simple family story either. De Imperatoribus Romanis notes a possible link with a governor under whom he may have served. That is a scholarly suggestion, not a secure fact about how he gained citizenship.
The safest picture is a man with a long army career who gained greater duties late in life. He did not follow the normal elite route of public office before becoming emperor. His military standing supplied what his family background did not.
The murder of Severus Alexander in 235
Severus Alexander had lost the trust of troops on the German frontier. Maximinus was training recruits who felt loyal to him. When the mutiny came near Mainz in 235, those soldiers offered him the throne. Alexander and his mother were killed. De Imperatoribus Romanis
This was not a vote by the whole empire. One army made a decision that other groups then had to confront. The Senate accepted the new ruler at first. World History Encyclopedia: Maximinus Thrax
But his standing among senators remained weak. A title granted after violence did not create trust.
Alexander had succeeded Elagabalus. With Alexander's death, the Severan house lost the throne. A commander whose claim rested on army service now stood at the head of the same state.
Frontier war under a soldier-emperor
Maximinus carried the war across the Rhine and then focused on the Danube. Campaigns against German groups, Dacians and Sarmatians helped build his image as an effective commander. He spent the reign near armies rather than returning to govern from Rome. De Imperatoribus Romanis
Success in war mattered because it kept soldiers loyal and justified his rule. Yet a reign built around campaigning had a cost. Troops needed pay, food and supplies. The people who funded them did not always see the benefit of a distant frontier victory.
He also faced plots within the army. One scheme aimed to cut a bridge behind him. Another group promoted Quartinus as a rival.
He suppressed both. The title of emperor did not free a soldier from the same military politics that had lifted him.
Revenue demands and the African revolt
The wars brought growing demands for money. Confiscations and harsh revenue collection angered landowners and the senatorial class. The sources are hostile. De Imperatoribus Romanis
So claims about personal greed need care. The pressure on property and taxes still helps explain the revolt.
In 238, landowners in Africa killed an imperial revenue official and proclaimed Gordian I. His son Gordian II joined him. The Senate backed the revolt and treated Maximinus as an enemy. It now had an alternative imperial house around which to organise resistance.
The Gordians' claim collapsed quickly. Capellianus, the governor of Numidia, defeated their forces. Gordian II died and his father killed himself. World History Encyclopedia
That did not make the Senate return to Maximinus. It chose Pupienus and Balbinus instead.
The Year of the Six Emperors
The label refers to 238. It counts Maximinus, the two Gordians, Pupienus, Balbinus and Gordian III. It does not mean that all six shared power peacefully or held equal power at one moment. World History Encyclopedia
Gordian III was first promoted as a junior figure while Pupienus and Balbinus ruled. His family name appealed to people in Rome who disliked the Senate's choices. Later, after the guard killed those two rulers, he became the surviving emperor.
The year shows how several power centres could collide. Provincial landowners, the Senate, city crowds and soldiers all mattered. None could simply command all the others. A successful claimant needed a coalition that would last beyond an initial acclamation.
Aquileia: the march that failed
Maximinus marched into Italy to crush the revolt. Aquileia closed its gates. He lacked supplies for a long siege. De Imperatoribus Romanis
His army could not force a swift surrender. Hunger and delay changed the troops' view of their commander.
Pupienus was raising forces from Ravenna while the siege continued. Maximinus's soldiers faced the risk of being trapped, with hostile forces ahead and too little food nearby. The emperor's army strength was no longer enough to settle the contest.
Soldiers killed Maximinus and his son Maximus in the camp. Their heads were sent to Rome. The force that had chosen him now removed him. His death was therefore a military rejection as well as a victory for the Senate's revolt.

Was Maximinus really a giant?
Exceptional height, strength and appetite
Status: Disputed
Tales of enormous size and eating appear in an unreliable tradition, including the Historia Augusta. Michael Meckler's biography accepts that he was imposing. But it stresses the lack of sound early evidence. De Imperatoribus Romanis
His precise height remains uncertain. Source: De Imperatoribus Romanis
Such stories make a vivid character. They are weaker evidence than the campaigns and rebellion. They should not support a medical diagnosis or a claim that his body explains his rule. His problem of rule was support, revenue and supply, not a measured height.
Verdict: Maximinus Thrax as Roman emperor
Maximinus Thrax was a capable military figure whose power depended on soldiers. His campaigns strained revenue, and elite opposition found a way to unite against him. At Aquileia, lack of supplies broke the bond with his own troops. His reign helps explain the rise and fall of the Roman Empire without turning one emperor into its single cause.
