In 1687 the
Marquis de Denonville led an army of French soldiers and
Huron warriors on a
punitive expedition against the
Iroquois through Irondequoit Bay, beginning the long enmity between the Iroquois and the French. After the
American Revolution, this area was part of the
Phelps and Gorham Purchase. The Town of Irondequoit was founded in 1839 when it separated from the town of
Brighton. During the last part of the 19th century, the north edge of the town was developed as a tourist and vacation area for Rochester residents, and was once known as the "
Coney Island of Western New York". After World War II, Irondequoit experienced significant population growth, with returning veterans looking for housing. Irondequoit became the first suburb in Monroe County to see substantial migration of residents from the city of Rochester, with the population growing from 23,376 in 1940 to 55,337 in 1960, an increase of 136%. Irondequoit remained the most-populated suburb in Monroe County until the 1970s, when it was surpassed by the town of
Greece, a community with three times the land area of Irondequoit. In 1965, Irondequoit became part of civil rights history by being part of the first totally voluntary
desegregation program in U.S. history. The Urban Suburban Interdistrict Transfer Program, which still operates today, was begun with 25 first graders from the inner city of Rochester who embarked on their K-12 education in the West Irondequoit school district. Ultimately, 15 of the original 25 students graduated together in 1977 as part of the first graduating class ever to go through a full 12 years of voluntary desegregation. The achievement was acknowledged in a letter from the White House and a notation in the U.S.
Congressional Record. The program has continued to expand and now includes additional suburban districts that are part of the Rochester metropolitan area. In 1991, Irondequoit established a
sister city relationship with
Poltava, in
Ukraine. Poltava is an Eastern Ukrainian city once known as "the Soul of Ukraine". The initiative was spearheaded by Irondequoit Town Supervisor Fred Lapple. His appointed committee chair, Tamara Denysenko, identified Poltava, Ukraine as Irondequoit's chosen Sister City. ==Geography==
