Antirent War at English => English (The Britannica Concise) Of Explained:
Civil protest from leaseholding farmers in upper New York state in the 1840s. The farmers resented outdated laws based on semifeudal leaseholding practices of the early Dutch estate owners. In 1839, when they revolted against attempts to collect back rent in Albany Co., 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 was forced to declare martial law. In 1846 a new state constitution abolished the leasehold system.
