Duke of Wellington vs Theodosius I

Wellington, then Sir Arthur Wellesley, led a British-Indian force to victory against the Maratha Confederacy at Assaye in India. Despite being outnumbered, his tactical skill secured British dominance in central India.

Wellington commanded British forces to defeat the French army at Vimeiro in Portugal. The victory halted the French invasion of Portugal and marked the beginning of the Peninsular War.

Wellington, commanding an Anglo-Allied army, defeated Napoleon Bonaparte at Waterloo in present-day Belgium. The battle ended the Napoleonic Wars and led to Napoleon's final exile to Saint Helena.

Wellington served as Prime Minister of the UK from 1828 to 1830. His government passed the Catholic Relief Act 1829, granting Catholic emancipation, but his opposition to parliamentary reform led to his resignation.

Theodosius I issued the Edict of Thessalonica, declaring Nicene Christianity the official state religion of the Roman Empire. All other forms of Christianity were deemed heretical, and pagan practices were increasingly suppressed.

Theodosius I ordered a massacre of thousands of citizens in Thessalonica in retaliation for the murder of a Roman general. The massacre led to his excommunication by Bishop Ambrose of Milan, and he later performed public penance.

Theodosius I issued a series of laws banning pagan worship, closing temples, and prohibiting sacrifices. The Olympic Games were abolished, and the Serapeum in Alexandria was destroyed. These actions accelerated the decline of paganism in the empire.

Theodosius I defeated the usurper Eugenius and his general Arbogast at the Battle of the Frigidus (modern River Vipava). The victory reunited the Roman Empire under a single ruler for the last time before its permanent division.

Upon his death, Theodosius I divided the Roman Empire between his two sons: Arcadius received the Eastern Empire and Honorius the Western Empire. This division became permanent, leading to the separate histories of the Byzantine and Western Roman Empires.
