(1839–46) Civil protest by leaseholding farmers in upper New York state.
Protesting outdated laws based on semifeudal leaseholding practices of the early Dutch estate owners, the leaseholders of Albany county in 1839 refused to pay back rent. The governor called out the militia to quell the violence. Sporadic acts of resistance against rent and tax collection spread across the state, and in 1845 the governor declared martial law. In 1846 a new state constitution abolished the leasehold system.
