In 1415, the Swiss Confederacy seized Aargau from the Habsburgs – but instead of becoming a unified canton, the territory was split up among the victors. For nearly four centuries, Aargau was a patchwork of subject territories ruled by Bern, Zürich, Lucerne, and jointly governed lordships. Religious division between Protestant and Catholic areas added another layer of complexity, shaping the region's identity until Napoleon finally unified it in 1803.
The 1415 Swiss Conquest
Seizing the Habsburg Heartland:
- 1415: Swiss Confederacy conquered eastern Aargau from the Habsburgs
- Exploited a conflict between the Habsburg duke and the Holy Roman Emperor
- Bern led the campaign alongside other cantons
- Major blow to Habsburg power in the region
Division of the Spoils:
Aargau was NOT unified – it was split into separate pieces:
1. Bernese Aargau:
- Bern took the largest share (western/southern Aargau)
- Governed as a subject territory – conquered land, not an equal canton
- Bern imposed Protestantism after the Reformation (1528)
- Included: Aarau, parts of the Baden region
2. Other Cantonal Possessions:
- Zürich controlled northeastern parts
- Lucerne had interests in southern areas
- Each ruling canton extracted revenue and imposed its laws
Common Lordships & Religious Split
The Jointly Ruled Territories:
Common Lordships (Gemeine Herrschaften):
- Some areas were governed jointly by multiple cantons
- Baden: Important town, ruled in rotation by 7–8 cantons
- Freie Ämter (Free Bailiwicks): Central-southern region, contested
- Bailiffs rotated from ruling cantons, creating complex administration
- No stable local governance – power was shared and distant
The Confessional Divide:
- After the Reformation, Aargau became religiously split:
- Protestant zones: Areas under Bern and Zürich
- Catholic zones: Freie Ämter, Fricktal (under Catholic cantons)
- Religion determined which canton ruled you
- Tensions persisted for centuries – a fault line still visible in modern Aargau's geography
- Freie Ämter remained Catholic (still the historic Catholic heartland today)
Baden had one of the most unusual governance arrangements in Swiss history! The town was ruled by 7–8 cantons in rotation, with a new bailiff arriving each year from a different canton. This meant no consistent laws, policies, or leadership – just a constantly changing administrator. It made Baden a fascinating crossroads where different Swiss traditions and laws intersected, but it also made stable development nearly impossible.
Remember ag_2 key facts: 1415 (Swiss conquest from Habsburgs, Bern led), Bernese Aargau (largest share, Protestant after 1528), Gemeine Herrschaften (jointly ruled territories, Baden rotated 7–8 cantons), Freie Ämter (Catholic, jointly governed), religious split (Protestant north/west, Catholic south/east). Aargau was fragmented for ~400 years after 1415.
