Cospaia lay under neither the Papal States nor Tuscany because the boundary agreed after the pledge of Sansepolcro to Florence followed a stream called Rio, and two streams bore that name.[1][2]

Republic of Cospaia
A tiny strip of land on the Tuscan–Papal border that, through a boundary-treaty ambiguity in the mid-15th century, lay outside both states' jurisdiction until the two governments divided it in 1826; tobacco was its main crop.

After Pope Eugenius IV pledged Sansepolcro to Florence (sources give 1440 or 1441), the boundary was set along a stream called Rio. Two streams bore that name, and the strip between them, with the village of Cospaia, fell under neither jurisdiction. The Italian state-archives record states that neither government resolved the matter by law or force, that no tribute was imposed, and that the community's only written law was the inscription Perpetua et firma libertas on a church. Farmers grew tobacco freely from the 17th century while cultivation in the Papal States was regulated, and smuggling flourished. In 1826 the papal and Tuscan governments divided the territory. No formal institutions of government are documented in the sources consulted.
Timeline
- 1440A papal pledge of Sansepolcro to Florence sets a boundary along a stream named Rio, leaving the strip around Cospaia outside both states (sources give 1440 or 1441). [S1]Established
- 1601From the 17th century onward, Cospaia's farmers are recorded freely cultivating tobacco. [S3]Established

- Jun 1826The papal delegate's notification of 28 June 1826 integrates Cospaia into the Papal States and lets residents keep growing tobacco under a quota. [S3]Established
Outcomes & controversies
A small farming community lived for nearly four centuries outside the fiscal and legal reach of both neighbouring states and became an early site of tobacco cultivation in the upper Tiber valley. It is an example of a jurisdictional gap created by a boundary error.
Post-mortem
In 1826 the papal and Tuscan governments agreed to divide Cospaia; its larger part joined the Papal States and residents were allowed to keep growing tobacco under a quota. The archival record notes that its fiscal autonomy had made it a haven for smugglers and that it was affected by Napoleonic-era changes.

From the 17th century Cospaia's farmers freely grew tobacco, whose cultivation in the Papal States was regulated; after 1826 residents kept the privilege of growing tobacco under a quota of half a million plants.[1]

In the years before 1826 Cospaia's location and fiscal autonomy made it a haven for smugglers, and in 1826 the papal and Tuscan governments agreed to divide it.[1]
