Ercildoun, population about 100, is an unincorporated community in East Fallowfield Township, Chester County, Pennsylvania, United States. The hamlet was founded by Quakers and was an early center of the abolitionist movement. In 1985 the entire hamlet, including 31 properties, was listed as a historic district on the National Register of Historic Places. Of these properties two were vacant land, 14 were significant buildings, ten were contributing buildings, and five buildings, built in the 1950s, were non-contributing. The Lukens Pierce House, an octagon house listed separately on the U.S. National Register of Historic Places, is located about half a mile northwest of the hamlet. Ercildoun is one of about ten hamlets in the township, which has no cities or towns, but has 31 sites listed on the National Register. It is one of the larger hamlets, located near the center of the township, and historically among the best known. The city of Coatesville is about 3 miles north.

Fulton became active as an officer of the county and state anti-slavery societies and attended national meetings on abolition. In its first annual report the Society stated that they had distributed 3,000 books and tracts and gathered signatures petitioning Congress to abolish slavery in the District of Columbia and the territories. The Anti-Slavery Society met in the Fallowfield Meetinghouse until the winter of 1844, when Abby Kelley and Charles Burleigh spoke at a meeting that was broken up by a mob of anti-abolitionists. About this time abolitionist halls were burned down in Philadelphia and Lancaster, both less than 40 miles away. The Quaker Meeting membership then banned the Anti-Slavery group from its meetinghouse. In 1845 an association of abolitionists purchased the
