On March 25, 1800, Greene County was created by the partitioning of Albany (360 Square Miles) and Ulster (270 Square Miles) counties, producing a county of 620 square miles (1,600 km2). On April 3, 1801, 90 square miles (230 km2) of land was transferred from Delaware and Ulster counties, raising the total area to 710 square miles (1,800 km2).
