History
A French missionary by the name of Father Gabriel de la Ribourde brought Catholicism to the Seneca area 175 years before St. Patrick's Parish was founded. In 1680, he was traveling with an exploratory party from Quebec when he was ambushed and killed by a band of Kickapoo Indians. A wooden cross marks the spot where Illinois’ first martyr to the Catholic faith is believed to have died (which is located next to St. Patricks Catholic Church).
Seneca was first settled by Jeremiah Crotty, an entrepreneur and contractor who helped build the Illinois and Michigan Canal. Crotty built the first residence in 1850 and established the town in 1854 with a post office in his name. Residents retained the name Crotty Town until 1957, when they incorporated the town as Seneca. Before 1957 Seneca was known as Crotty in paper but known locally as Seneca.
The village of Seneca, formerly named Crotty after its founder, Jeremiah Crotty, was incorporated in 1865. The town was created during the construction of the

Schools
Seneca has three schools split into two school districts: Seneca Grade School North Campus (pre-kindergarten - 4th grade) and Seneca Grade School South Campus (grades 5–8) make up District 170, while Seneca Township High School] (grades 9 - 12) is the lone school in District 160. Seneca High School houses students from Seneca as well as students from the nearby towns of Mazon, Illinois, Mazon, Verona, Kinsman, and Marseilles.
The 2005 Illinois State Board of Education's 2005 Illinois District Report Card shows that the Seneca High School was strongly funded - in large part through payments made by Commonwealth Edison's power generation plant located approximately ten miles south of Seneca. For example, the above cited 2005 high school district Report Card shows the Illinois State average instructional expenditure per pupil at $5,216, but Seneca was able to provide $8,647 in instructional expenditures per pupil. Similarly, while the state average operating expenditure per pupil was $8,786, Seneca was able to dedicate $17,305 per pupil, which is reflected in the grade school, middle school, and high school facilities. These payments made by Commonwealth Edison have since decreased along with the impact they once had.
