Antirent War,in U.S. history, tenant uprising in New York state. When Stephen Van Rensselaer, owner of Rensselaerswyck, died in 1839, his heirs attempted to collect unpaid rents. Tenants on the estate resisted, and an angry mob forcibly turned back a sheriff's posse that tried to evict them. Resistance to landlord authority quickly spread to landed estates throughout the Hudson valley; tenants disguised as Native Americans harassed landlord agents and sheriffs. When a deputy sheriff of Delaware co., N.Y., was killed (1845), Gov. Silas Wright declared a state of insurrection and called out the state militia. Armed resistance ended and the antirenters turned to politics. They helped elect a Whig, John Young, as governor of New York; the legislature passed ameliorative measures; and the 1846 state constitution outlawed future long-term leases. The Antirent War hastened the breaking up of the large landed estates as worried landlords began selling their holdings.
