Founding Federalist brings to life a figure whose contributions shape American political life even today. Vividly capturing the pivotal debates at Philadelphia in the summer of 1787, Toth shows how Ellsworth was a vital force in shaping the Constitution as a Federalist document, one that did not extinguish the role of the states even as it recognized the need for national institutions. The author illuminates what Ellsworth and other Founders understood to be the meaning of the new constitutional order—a topic highly relevant to twenty-first-century debates about the role of government. Toth, an attorney, also brilliantly analyzes Ellsworth’s most important legislative achievement: the creation of the U.S. federal court system.With this insightful new biography, Michael Toth has reclaimed a figure who made crucial contributions to a lasting creation: a federal republic.
