# Chinggis forces Xi Xia to submit in a first Tangut campaign

Date: 1209

## The fact

In 1209 Chinggis Khan forced Xi Xia to submit as a vassal after a campaign into Tangut country. Encyclopaedias date the submission. It is a settlement heading, not the later annihilation. Genghis Khan's documented role is: He invaded Xi Xia and took a vassal settlement rather than destroying the dynasty. Tangut rulers yielded tribute; 1226 annihilation is a later Fact.

## Context

Yellow River irrigation states were vulnerable to siege. Sharing the campaign with Mongol tumens is required. 1226 destruction remains a different Fact. The setting of Chinggis forces Xi Xia to submit in a first Tangut campaign is the public file around 1209-01-01. Shared offices, unnamed crews, printers, or later editors may appear without becoming this instrument. Driver [social-cohesion](/drivers/social-cohesion) is attached because the significance names a mechanism from this act, not because a standing list needed coverage.

Confidence is stated on the impact path, not hidden in adjectives. Do not merge 1209 vassalage with 1226 annihilation. Siege harm of 1226 stays on that row. Mixed effects of Chinggis forces Xi Xia to submit in a first Tangut campaign are separate paths.

Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.

The attached driver is social-cohesion. The welfare reading used in this dossier is improving. That reading is an impact-path choice, not a property stored on the Fact itself.
