In 1695, Thomas Powell bought about from local Indian tribes, including the Marsapeque, Matinecoc, and Sacatogue, for 140 English pounds. This land, which includes present day Bethpage, East Farmingdale, Farmingdale, Old Bethpage, Plainedge, Plainview, South Farmingdale, and part of Melville, is known as the Bethpage Purchase and is approximately east to west and north to south.
Powell called his land Bethphage, because it was situated between two other places on Long Island, Jericho and Jerusalem, just as the biblical town of Bethphage (meaning "house of figs") was situated between Jericho and Jerusalem. Today, the Long Island place formerly called Jerusalem is known as Wantagh and Island Trees, while the placename Jericho is unaltered. Over time, Bethpage was spelled without the second "H". Powell's 14 children split up his purchase and it evolved into several farming communities, and the one in this mostly central part of the purchase retained the name "Bethpage".
A railroad spur completed in 1873, known as the Bethpage Branch of the Central Railroad of Long Island, ran to a brickworks plant which had opened in Old Bethpage in the 1860s. The railway was built to transport bricks for the construction of Alexander Stewart's Garden City. For a few years, regularly scheduled passenger traffic also appeared in timetables, with the station being called Bethpage. The line was abandoned in 1942. Remnants of a locomotive turntable can be found in the woods of Bethpage State Park on the east side of Round Swamp Road. The brickyard continued operations under different owners until 1981, with different sections known variously as Bethpage Brickworks, Queens County Brick Manufacturing Company, Post Brick Company, and (after Nassau County split from Queens County in 1899) Nassau Brick Company. The pitted terrain at the brickworks was used in investigations by Grumman for digital mapping of Earth.
In 1908, William Kissam Vanderbilt II began construction of the Long Island Motor Parkway, one of the country's first highways. Eventually stretching from Queens, New York to Lake Ronkonkoma, New York, a portion of the parkway ran through Old Bethpage. Street names such as "Vanderbilt Lane", "Motor Parkway" and "Toll Place" serve as reminders. Segments of the old roadbed and some bridges can still be seen in some places, including Battle Row Campground, Bethpage State Park, and the Old Bethpage Village Restoration.
In 1932, under the auspices of Long Island State Parks Commissioner, Robert Moses, Bethpage State Park, was opened. The park and its is almost entirely within the hamlet of Old Bethpage. In 1936, the adjacent hamlet of Central Park changed its name to Bethpage. Following this name change, the hamlet originally called Bethpage resisted suggestions that it merge with the new Bethpage, and got approval from the post office to change its name to Old Bethpage, though it did not have its own post office until 1965. Bethpage State Park remained so named, leading some to mistakenly believe that the park is located mostly in Bethpage.
As tuberculosis was brought under control, the complex of Georgian style buildings was closed in the 1960s. Following its closure, the facility was given over to mixed use, including the establishment of a drug and alcohol rehabilitation center in 1976, and a branch of the Cornell Cooperative Extension. In 1999, Charles Wang, founder of Computer Associates purchased the property from the county for $23 million. Included in the purchase was 1535 Old Country Road, which now houses the corporate offices of the New York Islanders and New York Dragons, both of which are owned by Wang. In addition, the building is home to the Wang-created, Plainview Chinese Cultural Center.
In 1960, responding to Nassau County's rapid suburban expansion, the county announced plans for the development of the Nassau County Fire Service Academy. Located on Winding Road, the academy provides provides training to all Nassau County fire departments.
