Origins of the Yuezhi and Xiongnu Conflict
📌 The Yuezhi, initially semi-nomadic traders of jade and horses near the Gansu Corridor, grew wealthy but faced rivalry from groups like the Xiongnu and Wusun.
⚔️ In 220BC, combined pressure from the Yuezhi and Qin Dynasty forced the Xiongnu north, despite the Xiongnu potentially fielding 100,000 horse archers.
👑 Modu, a Xiongnu prince, escaped captivity by stealing a swift horse, returned a hero, was given command of 10,000 cavalry, and eventually assassinated his father to become ruler (Modu Chanyu) by 209BC.
💥 By 176BC, Modu's reorganized Xiongnu forces crushed the Yuezhi, leading to ultimate expulsion from the Gansu region after a final defeat where their king's skull was made into a drinking cup.

Yuezhi Migration and Formation of the Kushan Empire
🏃 The expelled Yuezhi migrated approximately 2,000 miles west over several decades, displacing the Saka people en route.
🛡️ The fleeing Saka attacked Bactria, leading to the destruction of the city of Alexandria on the Oxus and weakening the Greco-Bactrian Kingdom.
👑 The Yuezhi subsequently pushed south into Bactria, driving out the Saka and occupying the core territory, forming the Kingdom of Guishang (Kushans) around 30AD under Kujula Kadphises.
📈 Chinese estimates placed the Kushan state population at 400,000 Yuezhi capable of fighting, alongside roughly 1 million settled Iranians and Asiatic Greeks.

Kushan Expansion and Governance
⚔️ Kujula Kadphises expanded west, capturing the wealthy and strategic Kabul valley, providing access to India via the Hindu Kush, and challenged Parthia in 55AD.
🐎 Successor Vima Takto allied with Han China against Kangju forces; later, after being refused a marriage alliance, he launched an unsuccessful siege of Kashgar with 70,000 horsemen.
🐘 Vima Kadphises (successor from 100AD) expanded south into the Indus Valley, defeating Indian armies using horse archers against war elephants, and installed steppe warlords as governors to collect revenue, including spices and perfumes.
🐴 The Kushans actively engaged in commerce, with reports from a third-century envoy noting they shipped Bactrian horses by sea as far as Sumatra.

Kanishka and Cultural Diffusion
👑 Kanishka the Great (from ~127AD) expanded territories toward the Upper Ganges region, with his presence noted near Mathura and Patna.
☸️ Kanishka is believed to be the first Kushan Emperor to convert to Buddhism and became a major patron, convening a key Buddhist council in Kashmir to translate sutras into accessible Sanskrit.
🏗️ Kanishka funded the construction of a massive stupa near Purushapura, whose dome likely had a diameter of about 286 feet.
🌏 Kushan merchants utilized the Silk Road, acting as a primary conduit for transmitting Buddhism to China, evidenced by the work of the Kushan missionary Lokaksema who translated texts in the Han court (150-189AD).

Key Points & Insights
➡️ The rise of the Kushan Empire stemmed from the forced westward migration of the Yuezhi after repeated defeats by the Xiongnu.
➡️ Kujula Kadphises unified the five Yuezhi tribes around 30AD, establishing the state by subjugating rival Xihous (allied princes).
➡️ The Kushan military strength relied heavily on mounted forces, utilizing traditional horse archers alongside potential cataphract heavy cavalry elites.
➡️ The Kushans strategically used both military conquest (India) and political maneuvering (Kashgar succession) to secure trade wealth and expand influence.
