Seneca Falls was the site of the Seneca Falls Convention, a foundational event in the Women's Rights Movement. The town is believed by some to have been the inspiration for the fictional town of "Bedford Falls, N.Y." portrayed in filmmaker Frank Capra's classic 1940s film "It's a Wonderful Life".

The region was in the domain of the Cayuga tribe and visited by Jesuit missionaries in the 17th-century.^{[citation needed]}

The Cayuga were allies of the British and attacked American settlements from the outset of the revolution. The Sullivan Expedition of 1779 was sent to destroy native villages and kill the warriors.^{[citation needed]}

After the war, the village and surrounding land became part of the Central New York Military Tract, land reserved for veterans of the war. The north end of Cayuga Lake was set aside as a reservation for returning Cayuga tribal members.^{[citation needed]}

The first pioneers arrived around 1790. The first settlers chose the area for its easy access to water and close proximity to the Iroquois trail.

When the village was first incorporated in 1831, it was named after the series of small falls and rapids on the Seneca River which drains Seneca of the Finger Lakes. The river was partially canalized for navigation in 1818, and connected the lakes with the Erie Canal in 1828. The village was re-incorporated in 1837, 1860, and 1896 with new charters.^{[citation needed]}
