Foedus Cassianum

According to Roman tradition, the Foedus Cassianum (/ˈfiːdəs ˌkæʃiˈeɪnəm/ in English) or the Treaty of Cassius was a treaty which formed an alliance between the Roman Republic and the Latin League in 493 BC after the Battle of Lake Regillus. It ended the war between the Latin League and Rome, placing Rome as equal in power to all of the members of the League combined.

The treaty was significant in serving as a model for later treaties between Rome and other Italic polities, outlining the terms of mutual assistance and equality of status within the defensive alliance.^[1]
