. Several alternate names had been considered for the county, including "Bryant", " Matinecock" (a village within the county currently has that name), "Norfolk" (presumably because of the proximity to Suffolk County), and "Sagamore". However, "Nassau" had the historical advantage of having at one time been the name of Long Island itself, and was the name most mentioned after the new county was proposed in 1875.

by the northern portions of the Town of Hempstead. Nassau County was formed in 1899 by the division of Queens County, after the western portion of Queens had become a borough of New York City in 1898, as the three easternmost towns seceded from the county. When the first European settlers arrived, among the Native Americans to occupy the present area of Nassau County were the Marsapeque, Matinecoc, and Sacatogue. Dutch settlers in New Netherland predominated in the western portion of Long Island, while English settlers from Connecticut occupied the eastern portion. Until 1664, Long Island was split, roughly at the present border between Nassau and Suffolk counties, between the Dutch in the west and Connecticut claiming the east. The Dutch did grant an English settlement in Hempstead (now in western Nassau), but drove settlers from the present-day eastern Nassau

. The 1850 census was the first in which the combined population of the three western towns (Flushing, Jamaica, and Newtown) exceeded that of the three eastern towns that are now part of Nassau County. Concerns were raised about the condition of the old courthouse and the inconvenience of travel and accommodations, with the three eastern and three western towns divided on the location for the construction of a new one. Around 1874, the seat of county government was moved to Long Island City from Mineola. As early as 1875, representatives of the three eastern towns began advocating the separation of the three eastern towns from Queens, with some proposals also including the towns of Huntington and Babylon (in Suffolk County). In 1898, the western portion of Queens County became a borough of the

As part of the city consolidation plan, all town, village, and city (other than NYC) governments within the borough were dissolved, as well as the county government with its seat in Jamaica. The areas excluded from the consolidation included all of the Town of North Hempstead, all of the Town of Oyster Bay, and most of the Town of Hempstead (excluding the Rockaway Peninsula, which was separated from the Town of Hempstead and became part of the city borough).

, the three towns were separated from Queens County, and the new county of Nassau was constituted. In preparation for the new county, in November 1898, voters had selected Mineola to become the county seat for the new county (before Mineola incorporated as a village in 1906 and set its boundaries almost entirely within the Town of North Hempstead), winning out over Hicksville and Hempstead. The Garden City Company (founded in 1893 by the heirs of Alexander Turney Stewart) donated four acres of land for the county buildings in the Town of Hempstead, just south of the Mineola train station and the present day village of Mineola. The land and the buildings have a Mineola postal address, but are within the present day Village of Garden City, which did not incorporate, nor set its boundaries, until 1919. In 1917, the hamlet of Glen Cove was granted a city charter, making it independent from the Town of Oyster Bay. In 1918, the village of Long Beach was incorporated in the Town of Hempstead. In 1922, it became a city, making it independent of the town. These are the only two

Law enforcement

County police services are provided by the Nassau County Police Department. The cities of Glen Cove and Long Beach, as well as a number of villages, are not members of the county police district and maintain their own police forces. The following village police departments exist in Nassau County: Brookville (Brookville P.D. provides police protection for Brookville, Matinecock, Mill Neck and Cove Neck), Centre Island, Floral Park, Freeport, Garden City, Great Neck Estates, Hempstead, Kensington, Kings Point, Lake Success, Lynbrook, Malverne, Muttontown-Upper Brookville, Old Brookville, Old Westbury, Oyster Bay Cove, Rockville Centre and Sands Point. The Port Washington Police District is not a village department but is authorized by a special district, the only such district in the State of New York. These smaller forces make use of such specialized county police services as the police academy and the aviation unit. All homicides in the county are investigated by the county police, regardless of whether or not they occur within the police district. In June 2011, the Muttontown Police Department commenced operations. The Old Brookville Police had formerly provided police services to the Village of Muttontown. On June 1, 2022, the Old Brookville Police Department reverted to serving only the Village of Old Brookville and moved its headquarters to the grounds of the Old Brookville village hall. The Village of Brookville formed a new police department, established headquarters on the grounds of the Brookville Nature Park and assumed policing duties for the villages of Brookville, Matinecock, Mill Neck and Cove Neck, that were formerly served by the Old Brookville Police Department. The Village of Upper Brookville joined the Muttontown Police Department which was subsequently renamed the Muttontown-Upper Brookville (MUB) Police Department. The former Old Brookville Police headquarters is now the Upper Brookville village hall and also a substation for the Muttontown-Upper Brookville Police Department. In 2006, village leaders in the county seat of Mineola expressed dissatisfaction with the level of police coverage provided by the county force and actively explored seceding from the police district and having the village form its own police force. A referendum in December 2006 decisively defeated the proposal. Since the Long Island State Parkway Police was disbanded in 1980, all of Nassau County's state parkways have been patrolled by Troop L of the New York State Police. State parks in Nassau are patrolled by the

s. The Nassau County Auxiliary Police are a unit of the Nassau County Police Department. These volunteer police officers are assigned to 1 of 38 local community units and perform routine patrols of the neighborhood. They provide traffic control for local parades, races and other community events. Auxiliary Police officers are empowered to make arrests for crimes that occur in their presence. Nassau County Auxiliary Police are required to complete a 42-week training course at the Nassau County Police Academy. Qualified officers are offered Emergency Medical Technician (EMT) training. Auxiliary Police officers are certified and registered by the New York Division of Criminal Justice Services as full-time "peace officers". The City of Long Beach has an independent auxiliary police force which is part of its municipal police force. These officers are represented by the Auxiliary Police Benevolent Association of Long Island.

Politics

For most of the twentieth century, residents of Nassau County and neighboring Suffolk County primarily supported the Republican Party in national elections.

Democratic strongholds also include several low income municipalities in the central portion of the county, such as the Village of Hempstead, Roosevelt, Uniondale and New Cassel, as well as in a few waterfront communities on the South Shore, such as the City of Long Beach and the Village of Freeport. Republican voters are primarily concentrated in the middle to upper middle class southeastern portion of the county, which developed during the "post-war boom era". Heavily Republican communities such as Massapequa, Massapequa Park, Seaford, Wantagh, Levittown, Bethpage, and Farmingdale are the political base of many county GOP officials such as former Congressman Peter T. King and former County Executive Edward P. Mangano. In the western portion of the county, wealthy Garden City is solidly Republican, as is the middle-class community of Floral Park. Additionally, some of the more rustic areas of the North Shore, particularly in the Town of Oyster Bay usually vote for the GOP. Areas of the county containing large numbers of swing voters include East Meadow, Oceanside, and Rockville Centre on the South Shore and Mineola on the North Shore. Several areas have changed in partisan affiliation. Formerly Democratic strongholds such as the Five Towns and parts of Great Neck have trended to the GOP while previously Republican areas such as Elmont, Valley Stream and Baldwin have become Democratic bastions.

In August 2024, Nassau County passed into law a ban on wearing face masks in public, making it a misdemeanor subject to a $1,000 fine and up to one year in prison to wear a facial covering in public, a move that was criticized by the New York Civil Liberties Union as a "dangerous misuse of the law to score political points." The law does not apply to facial coverings "worn to protect the health or safety of the wearer," but does appear to ban wearing a mask in order to protect the health or safety of others, including persons with compromised immune systems.
