Swiss Confederacy Territorial Expansion and Consolidation of Power (1430s)

Timeline

1. 1431–1436Zurich · SwitzerlandThrough purchase and annexation Zurich expanded its control over surrounding countryside and rights of passage, and strengthened alliances with towns such as Solothurn. The city commune's growing economic power raised its voice within the Confederacy while intensifying conflicts of interest with Habsburg counts and neighboring lords.
2. 1435–1439Eastern Swiss frontier · SwitzerlandThe Confederacy's cantons engaged in ongoing armed conflict and raiding counterstrikes against Habsburg Austrian forces on the eastern frontier. Swiss infantry tactics proved advantageous in small and medium engagements, weakening the empire's effective control over Swiss lands and further enhancing the Confederacy's military autonomy.
3. 1439–1440Zurich · SwitzerlandRelations between Zurich and fellow Confederacy members such as Schwyz deteriorated over disputes about territory and alliance policy, and the Old Zurich War broke out in 1440. The diplomatic rupture of 1439–1440 marked the open surfacing of internal Confederacy conflicts, but a decade of expansion had already made Switzerland a military-political entity to be reckoned with in Central Europe.
