Ban Chao vs Lysander

Ban Chao led a small force of Han troops and local allies to defeat the Xiongnu and their client states in the Tarim Basin. He reestablished Chinese control over the city-states of the Silk Road, securing trade routes and tribute from kingdoms like Kashgar and Khotan.

The Kushan Empire (Yuezhi) invaded the Western Regions with a large army. Ban Chao, with limited forces, used a scorched-earth strategy and cut off the Kushan supply lines, forcing them to retreat and sue for peace. This victory secured Han dominance in Central Asia.

Emperor He of Han appointed Ban Chao as Protector General of the Western Regions, a position that gave him authority over all Han territories and allies in Central Asia. He held this post for over a decade, maintaining peace and Chinese influence from the Pamirs to the Gobi Desert.

Ban Chao dispatched his envoy Gan Ying to explore the Roman Empire (Da Qin). Gan Ying reached the Persian Gulf but was told by Parthian merchants that the sea voyage was too dangerous, turning back. This was the closest a Chinese envoy came to Rome in antiquity.

Lysander, commanding the Spartan fleet, decisively defeated the Athenian navy at Aegospotami in the Hellespont. He captured nearly the entire Athenian fleet and executed thousands of Athenian prisoners, effectively ending Athenian naval power and the Peloponnesian War.

After Aegospotami, Lysander blockaded Athens by sea and forced its surrender. He imposed harsh terms: the destruction of the Long Walls, the surrender of the fleet, and the installation of the pro-Spartan oligarchy of the Thirty Tyrants, ending the Peloponnesian War.

Lysander oversaw the establishment of the Thirty Tyrants, a pro-Spartan oligarchic regime in Athens. This government executed political opponents and confiscated property, leading to widespread terror until its overthrow in 403 BC.

Lysander established pro-Spartan oligarchic governments (decarchies) in many former Athenian subject cities across the Aegean and Asia Minor. These regimes were loyal to Sparta and Lysander personally, extending Spartan influence but also creating resentment.
