+The Silk Road was a network of overland trade routes connecting China to the Mediterranean world, facilitating the exchange of goods, ideas, religions, and technologies for over 1,500 years. It was not a single road but a web of interconnected routes across Central Asia, with no single traveler traversing the full length. [^3]

+## Key Empires and Intermediaries
+- The **Han dynasty** (China) and **Roman Empire** were the primary producers and consumers of silk, but direct contact between them was rare [^3]
+- The **Parthian Empire** (~247 BCE – 224 CE) controlled the middle section of the route and acted as the principal intermediary between Rome and China, profiting from transit trade @t[~247 BCE..224 CE] [^4]
+- The **Kushan Empire** (1st–3rd century CE) facilitated trade across Central Asia and the Indian subcontinent, connecting the overland and maritime routes @t[~30 CE..375 CE] [^3]
+- **Sogdian merchants** from Samarkand dominated commercial activity along the route from roughly the 4th to 8th century CE, operating trading colonies as far east as China @t[~300 CE..~750 CE] [^5]

 ## Cultural Exchange
-- Buddhism spread from India to China via the Silk Road
-- Nestorian Christianity, Manichaeism, and Islam traveled eastward
-- Technologies transferred: Papermaking, gunpowder (later), glassmaking
-- Diseases also spread, possibly including plague [^2]
+- Buddhism spread from India to China via the Silk Road, carried by monks and merchants from roughly the 1st century CE onward @t[~1 CE..~400 CE] [^1]
+- Nestorian Christianity, Manichaeism, and Islam traveled eastward in later centuries
+- Technologies transferred: Papermaking (China → West), glassmaking (West → East), and later gunpowder
+- Diseases also spread along the routes, possibly including the Antonine Plague (165–180 CE) and Plague of Cyprian (249–262 CE) [^2]

+## Maritime Silk Road
+A complementary sea route — the Maritime Silk Road — connected China's southern ports to Southeast Asia, India, the Arabian Peninsula, and East Africa, beginning by the 2nd century BCE. [^6] During the Han dynasty, maritime trade relations with Southeast Asia and India were established alongside the overland routes.
 
 ## Key Periods
-- Han dynasty (206 BCE – 220 CE): Zhang Qian's missions opened the route (~130 BCE) @t[206 BCE..220]
-- Kushan Empire (1st–3rd century CE): Facilitated trade across Central Asia
-- Roman demand for Chinese silk drove trade westward
+- **Han dynasty** (206 BCE – 220 CE): Zhang Qian's first mission to the Western Regions in 138 BCE (dispatched by Emperor Wu) opened diplomatic contact; his second mission followed in 119 BCE. These missions catalyzed the formal opening of the route ~130–114 BCE. @t[206 BCE..220 CE] [^1]
+- **Kushan Empire** (1st–3rd century CE): Facilitated trade across Central Asia @t[~30 CE..375 CE]
+- **Pax Romana / Pax Sinica** (~50 BCE – 250 CE): The four empires of Rome, Parthia, Kushan, and Han simultaneously stable, enabling peak ancient Silk Road trade @t[~50 BCE..~250 CE] [^4]
+- Roman demand for Chinese silk was so great that Roman writers complained of gold draining eastward [^2]
