the Penn Square location at the intersection of Broad Street and Market Street (then known as High Street) where it now stands, preferring instead that it be built in Washington Square, near Independence Hall. Lea believed that the project cost too much, and was angered by the political corruption involved in the awarding of contracts and purchase of building materials. Lea planned and held a large public meeting to recruit support for his alternative to the Penn Square project. In 1870, he helped initiate the National Republican League to prevent Ulysses S. Grant's third term as president of the United States. The National Republican League chose Lea as its president in 1880 (the year he retired from his publishing business) and five years later, Lea served as president of the Association of Republicans and Independents. In 1891 he helped found "The Reform Political League of Pennsylvania", with Herbert Welsh as president, himself and Justus C. Strawbridge as vice-presidents, and Charles E. Richardson as secretary. Lea joined with others in 1884 and filed a lawsuit to oppose building a large slaughterhouse on the Schuylkill River at Thirtieth and Spruce streets on land owned by the Pennsylvania Railroad Company, citing the pollution of the river, the stench, and devaluation of properties near the plant. He also opposed the construction of the Market Street elevated train, over properties he owned on Market Street, as well as building the "boulevard" from City Hall northwest to Fairmount Park, where the Philadelphia Museum of Art was later built. In 1888, Lea doubled the size of the reading rooms and book shelves at the Philadelphia Library. In 1897, he built several buildings for the Pennsylvania Epileptic Hospital and Colony Farm in Oakbourne, Pennsylvania. Historian Lea focused on church history in the later Middle Ages, and on institutional, legal, and ecclesiastical history, as well as magic and witchcraft. He also did significant work on the history of the Italian city-states. His active writing career on historical subjects spanned more than fifty years, during which Lea published ten books and numerous articles. His literary reputation rests largely on those books. Highly disciplined work habits (and the ability to purchase manuscripts in Europe and Latin America and have them shipped to Philadelphia) led Lea to continue writing despite headaches and eye problems. His productivity increased during his final twenty-five years after he retired as a publisher and built an extension
