Maroboduus vs Prusias I

Maroboduus signed a treaty with the Roman Empire under Emperor Augustus, recognizing Roman supremacy. In return, Rome recognized his kingdom and provided diplomatic support, allowing him to focus on expanding his influence among Germanic tribes.

Maroboduus led the Marcomanni tribe from the Main River region to Bohemia, where he established the first organized Germanic kingdom. He built a centralized state with a professional army and fortified settlements.

Maroboduus fought a war against Arminius, the Cheruscan leader who had destroyed three Roman legions at Teutoburg Forest. The conflict ended in a stalemate, with neither side able to achieve a decisive victory.

Maroboduus was overthrown by a rebellion led by the noble Catualda, who was supported by the Goths. He fled to Rome and was granted asylum by Emperor Tiberius, spending the rest of his life in exile in Ravenna.

Prusias I besieged the Greek city of Byzantium, forcing it to pay tribute and acknowledge Bithynian supremacy. This campaign expanded Bithynian influence along the Bosporus and the Black Sea coast.

Prusias I waged war against Eumenes II of Pergamon, allying with the Galatians. The war ended with a Roman-brokered peace that forced Prusias to cede territory and pay indemnities, weakening Bithynia's position.

Prusias I granted asylum to the Carthaginian general Hannibal, who had fled from the Seleucid court after the defeat at Magnesia. Hannibal served as a military advisor to Prusias, helping him in conflicts against Pergamon.
