Alexander the Great vs Dorgon

Alexander led his Macedonian army across the Hellespont into Asia Minor and defeated a Persian force under local satraps at the Granicus River. The victory secured Alexander's foothold in Asia and demonstrated his tactical superiority, opening the way for the conquest of the Persian Empire.

Alexander's army defeated the Persian king Darius III at Issus in Cilicia. Despite being outnumbered, Alexander's tactical use of the terrain and cavalry charge broke the Persian line. Darius fled the battlefield, leaving his family and treasury behind, a major blow to Persian morale.

Alexander besieged the island city of Tyre for seven months, constructing a causeway to breach its walls. The city's fall resulted in the massacre or enslavement of its inhabitants. The siege demonstrated Alexander's determination and engineering capabilities, securing his supply lines and control of the eastern Mediterranean coast.

Alexander faced Darius III at Gaugamela in Mesopotamia with a massive Persian army. Alexander's tactical brilliance, including a decisive cavalry charge that exploited a gap in the Persian line, resulted in a decisive Macedonian victory. Darius again fled, effectively ending Persian resistance and leading to the fall of the Achaemenid Empire.

Alexander founded the city of Alexandria on the Mediterranean coast of Egypt. He personally selected the site and oversaw the initial planning. Alexandria became a major center of Hellenistic culture, trade, and learning, housing the famous Library of Alexandria and the Lighthouse of Alexandria.

Alexander crossed the Indus River and defeated King Porus at the Battle of the Hydaspes. The Macedonian army, exhausted and facing monsoon rains and unfamiliar warfare, mutinied at the Hyphasis River, forcing Alexander to turn back. This campaign marked the easternmost extent of his conquests.

Upon the death of Hong Taiji, Dorgon was appointed as regent for the young Shunzhi Emperor. This position gave him effective control over the Qing government and military, enabling him to direct the conquest of Ming China.

Dorgon allied with Ming general Wu Sangui to defeat Li Zicheng's rebel forces at Shanhai Pass. This victory allowed Qing forces to enter Beijing and establish the Qing dynasty as the ruling power in China.

Dorgon led Qing forces in a campaign against the Southern Ming regime, capturing Nanjing and defeating the Hongguang Emperor. This campaign extended Qing control over the Yangtze River valley and weakened Ming loyalist resistance.

Dorgon mandated that all Chinese men adopt the Manchu queue hairstyle as a sign of submission to Qing rule. This policy caused widespread resentment and resistance, but was enforced to consolidate Qing control over Han Chinese subjects.

Dorgon died suddenly while hunting. After his death, the Shunzhi Emperor accused him of plotting to usurp the throne, stripped him of all titles, and had his corpse mutilated. This posthumous purge reflected court factional struggles.
