The Mongols built the largest connected land empire in history, ruling across much of Asia and into the lands of the Rus. Their conquests destroyed cities and displaced people. Protected routes and postal relays also helped goods, messages and knowledge travel.

## Ready when they can

- Describe the empire's broad extent and name two regions under Mongol rule, distinguishing rule from an invasion
- Give one military advantage of Mongol armies, such as mobile horse archers or the use of siege specialists
- Explain how protected routes or postal relays helped goods, messages or knowledge move

## Lesson: The Mongols: Destroyers and Joiners

Temujin took the title Chinggis Khan in 1206 after a meeting called a kurultai confirmed his leadership. He and his successors built the largest connected land empire in history. It included China, Central Asia, Persia and lands of the Rus. Korea submitted to Mongol rule. Armies invaded Hungary, but did not establish lasting rule there.

Many Mongol soldiers were skilled riders and archers. Their mobility helped them choose where to attack and withdraw. Opponents also used cavalry, so speed was not their only advantage. Scouts and coordinated forces helped plan attacks. Specialists from conquered peoples built and used siege machines to attack walled cities.

Conquest caused great harm. Mongol armies destroyed cities, killed many inhabitants and enslaved people. Baghdad was sacked in 1258. Some skilled workers were spared but forced to move and work for Mongol rulers. A history of the empire needs evidence about these human costs as well as its trading connections.

Like the sea routes you have studied, overland routes linked distant trading places. Mongol rulers protected merchants on some routes, reducing robbery risks. Official messages travelled through a postal relay called the yam. Riders could obtain fresh horses at stations. Travel still had dangers, and local people had to help supply the stations.

*(drawing: Fresh horses helped official messages move along the relay.)*

Ruling required records as well as armies. Chinggis Khan had the Uyghur script adapted for writing Mongolian. Officials could use writing to keep records. This was an adaptation of an existing script, not a writing system created without earlier influences.

During the later 1200s, the empire divided into four main khanates, or territories ruled by khans. These included Yuan China, the Ilkhanate in Persia, the Chagatai Khanate in Central Asia and the Golden Horde in the northwest. Trade continued across some borders, but conflicts could interrupt it. A closed border could force a traveller to wait or find another route.

**Recap.** Mongol armies combined mobility with siege skills. Conquest caused destruction and forced movement, while protected routes and postal relays supported travel.
