Servius Tullius vs Tigranes II of Armenia

Servius Tullius instituted the first Roman census, dividing the population into five classes based on wealth. He also reorganized the army and created the Centuriate Assembly, a new political body where voting power was weighted by property, replacing the old tribal system.

Servius Tullius divided Rome into four urban tribes and several rural tribes based on geography, not kinship. This reorganization formed the basis for the Tribal Assembly, which handled administrative and legislative matters, and weakened the power of the old patrician gentes.

Servius Tullius reformed the Roman army, organizing soldiers into centuries based on their wealth class. This created a more professional and effective military force, with each century providing its own equipment, and established the comitia centuriata as a military assembly.

Servius Tullius built the Servian Wall, a massive defensive wall around Rome, enclosing the seven hills. This wall protected the city from external attacks and defined the urban boundary, becoming a symbol of Roman strength and security.

Servius Tullius was murdered by his son-in-law, Lucius Tarquinius Superbus, who conspired with Tullia, Servius's daughter. Tarquinius seized the throne after the assassination, and Tullia drove her chariot over her father's body, an act that became infamous in Roman history.

Tigranes II was crowned King of Armenia after being released as a hostage by the Parthian king Mithridates II. He immediately began expanding Armenian territory, conquering Sophene and other regions, laying the foundation for his empire.

Tigranes II conquered the remnants of the Seleucid Empire, annexing Syria and Cilicia. This expansion brought Armenia to its greatest territorial extent, stretching from the Caspian Sea to the Mediterranean, and made Tigranes a major power in the Near East.

Tigranes II founded the city of Tigranocerta as the new capital of his empire. The city was built with a mixed population of Armenians, Greeks, and others, and became a major Hellenistic center of trade and culture in the region.

Roman forces under Lucullus defeated Tigranes II's army at the Battle of Tigranocerta. The defeat led to the loss of Tigranes' newly conquered territories and the sacking of his capital, marking the beginning of the decline of the Armenian Empire.

After further defeats, Tigranes II submitted to the Roman general Pompey. He was allowed to retain Armenia proper as a Roman ally but was forced to give up all his conquests, including Syria, Cilicia, and Sophene, reducing Armenia to its pre-imperial borders.
