The land currently comprising Lyndhurst was part of the Western Reserve, obtained via treaty with the Iroquois tribe in 1796 by the Connecticut Land Company. In 1797, Moses Cleaveland named the area east of the Cuyahoga River Euclid, after the Greek Mathematician and Patron Saint of surveyors. Euclid Township was officially formed in 1809. Despite this, Lyndhurst's population consisted mostly of Native American Indians until after the War of 1812. In 1828 Euclid Township was divided into nine districts, with the present area of Lyndhurst becoming district four. From 1877 the main traffic corridor has been Mayfield Road. Initially a wood-planked toll road, it is now home to many retail establishments and restaurants. The earliest industry was farming. As the area grew, it became known as Euclidville Village, the name changing to Lyndhurst Village in 1920 before Lyndhurst was formally incorporated as a city in 1921. Population growth in Lyndhurst, which tapered during the Great Depression, skyrocketed during the postwar period, driven by both the baby boom and white flight from the urban center of Cleveland. Lyndhurst's population peaked in the 1970s. By 1980, lacking large tracts of available land for development, and with a population shift to exurban communities, the population of Lyndhurst began to shrink. The 2010 population of Lyndhurst was 29% less than its peak during the 1970s.
