What was happening during the Mongol Empire?

While Genghis Khan's armies swept across Asia, crusaders, Baltic knights, and Japanese clans were fighting wars of their own — see them side by side.

We tend to picture the Mongol Empire as a single story moving west across the map. Annalium shows it as one thread in a crowded century. When the Mongols invaded the Khwarazmian Empire between 1219 and 1221 — the campaign that produced the sieges of Bukhara, Samarkand, Merv, and Nishapur — the rest of Eurasia was not standing still. Far to the northwest, German crusaders and Baltic peoples were locked in their own conflict, with the Battle of Lyndanisse fought in 1219 near modern Tallinn. The same span saw the long Siege of Damietta in Egypt, part of the Fifth Crusade.

Push the timeline and the simultaneity sharpens. The Mongol conquest of the Jin dynasty opened in 1211 in northern China and dragged on for more than two decades. In those same years Japan saw the Battle of Uji in 1221, an episode of the Jōkyū War between the imperial court and the Kamakura shogunate. And in 1223, as Mongol generals Jebe and Subutai probed the western steppe, the Battle of the Kalka River brought a coalition of Rus' princes to a catastrophic defeat — a first, distant warning of what was coming to Eastern Europe.

That arrival came in the late 1230s. The Battle of the Sit River in 1238 and the sieges of Ryazan and Kolomna mark the Mongol invasion of the Rus' principalities. Read across the map at any single year and the pattern holds: the Mongols were one expanding power among many, and the wars of the Baltic, the Levant, Korea, and Japan ran on their own clocks. Annalium's value is letting you hold all of them in view at once, so "during the Mongol Empire" stops being a backdrop and becomes a specific, datable world.
