In Albany County, New York, the Antirent War, also known as the Helderberg War after the mountain group in the area, broke out when tenant farmers resisted the attempts of the descendants of Stephen Van Rensselaer to collect back rent. Sporadic conflicts contained until 1846, when Gov. Silas Wright moved to solve the crisis through legislation. The result was the New York State constitution of 1846, which outlawed the practice of perpetual leases on the old Dutch patroonships, and provided for a just settlement of the conflict.
