Julius Caesar vs Yelu Abaoji

Caesar, as proconsul of Gaul, launched a series of campaigns that conquered all of Gaul (modern France, Belgium, and parts of Switzerland). He fought numerous battles, including against the Helvetii, the Belgae, and the Gallic chieftain Vercingetorix. The wars brought immense wealth and a loyal army to Caesar.

Caesar led Legio XIII across the Rubicon River into Italy, defying the Roman Senate's order to disband his army. This act triggered a civil war against Pompey and the Optimates, ultimately leading to Caesar's dictatorship and the end of the Roman Republic.

Caesar's outnumbered army defeated the larger forces of Pompey the Great at Pharsalus in Greece. Caesar's tactical use of a reserve line to counter Pompey's cavalry charge proved decisive. Pompey fled to Egypt, where he was assassinated, leaving Caesar as the undisputed master of the Roman world.

The Roman Senate appointed Caesar dictator perpetuo (dictator for life), granting him unprecedented personal power. This move concentrated military, legislative, and judicial authority in one person, effectively ending the Roman Republic's traditional system of checks and balances and alarming many senators.

A group of Roman senators, led by Marcus Junius Brutus and Gaius Cassius Longinus, stabbed Caesar to death at a meeting of the Senate in the Theatre of Pompey. The assassination was intended to restore the Republic, but instead triggered another civil war that led to the rise of the Roman Empire.

Yelu Abaoji was elected khagan of the Khitan tribes, unifying them under his leadership. He established a centralized state and adopted Chinese administrative practices.

Yelu Abaoji proclaimed himself emperor, founding the Liao dynasty. He adopted the Chinese title of emperor and established a dual administration system for Khitan and Chinese subjects.

Yelu Abaoji ordered the creation of a writing system for the Khitan language, based on Chinese characters. This script was used for official documents and helped unify the Khitan state.

Yelu Abaoji led a campaign that conquered the Korean kingdom of Bohai, incorporating its territory into the Liao empire. This expanded Liao's influence into Manchuria and Korea.

Yelu Abaoji died while returning from the conquest of Bohai. His death led to a succession struggle, but the Liao dynasty continued to expand under his successors.
