The historical background for Monroe County dates back to 1683 when counties were established in the state. This area was then part of the enormous Albany County which took in all of what is now Vermont and the northern part of New York. It also, in effect, extended clear to the Pacific Ocean. When Cumberland County was established on 3 July 1766, it was reduced in size. Again, on 16 March 1770, it was changed when Gloucester County was formed. On 12 March 1772, Albany County was further divided into three parts. One part remained as Albany County. Tryon County took up the western portion with no western border as that part of the former Albany County had previously done. The eastern border of that county was near the now city of Schenectady. It was named for William Tryon, the colonial governor of New York. This area is now designated into 37 counties showing the huge size of the county during that time period. In 1784, the name of Tryon County was changed to Montgomery County in honor of Richard Montgomery, the Revolutionary War hero. Ontario County was created from Montgomery County in 1789. The new county was very large, including land now occupied by 14 present-day counties. Genesee County was split from Ontario County in 1802 and it contained parts of what would later become nine present-day counties.

Monroe County was finally formed from parts of both Genesee and Ontario Counties on 23 February 1821. The county was named for President James Monroe. Many towns and villages were already in place along with around 28,000 settlers when the county was established. Rochester was named the county seat and remains such to this day. The area grew industrially due to its proximity to the Genesee River and the Erie Canal. What was a basically agricultural economy and now focused more on technology.

The early inhabitants of the area were Native Americans, the Algonquin and the Seneca. The Seneca were known as the "Keepers of the Western Door." They controlled trade for a wide area. After the Revolutionary War, soldiers returned to their homes telling about the good soil and nice area in this part of New York. Many returned with their famiies to settle the area.

Businessmen, Oliver Phelps and Nathaniel Gorham, purchased land here, but couldn't negotiage for the land west of the Genesee River. Finally Phelps was able to gain possession with a small area for the construction of mills. This became known as the mill seat tract. The first mill was owned by Ebenezer Allan in 1789. As the area grew, there also became a need for more organization. In 1796, the area east of the Genesee River became known as Northfield and that area to the west became Northampton in 1797. Northfield became know by many other names over the years. Some of the new towns were Boyle, Penfield, Perinton, Brighton, Mendon and Rush. At this time, the towns were all part of Ontario County. Similar growth was taking place on the west side of the Genesee with not only Northampton, but also Parma, Riga, Gates, Sweden, Ogden and many other towns. Those on the west side were part of Genesee County. Finally, populations had increased so much that the people wanted government closer to where they lived. Proposals were made for a new county in the early 1800's. The old counties weren't happy about letting go of all the progress and new settlement which was occurring, but the legislators voted to approve the new county on 23 February 1821. This brand new county was recorded until 6 April 1821. It had 675 square miles and had fourteen original towns: Brighton, Gates, Clarkson, Henrietta, Mendon, Ogden, Pama, Penfield, Perinton, Pittsford, Riga, Rush, Sweden and Wheatland. Rochester was the first county seat. The supervisors met in homes and businesses until the courthouse was finished. The land was donated by the founders of Rochester, Fitzhugh, Carroll and Rochester. The cornerstone was laid on 4 September 1821. A second courthouse was later built, but also became too small and cramped. It was torn down. The third courthouse was begun in 1894.
