Founding Brothers is a work of historical non-fiction, focusing on key moments both in post-revolutionary America and in the lives of the Founding Fathers. Ellis examines how the specific relationships of the Founding Fathers influenced, or were influenced by, the turbulent period in which they lived. Separated into seven sections, the book uses the lenses of hindsight and foresight to understand both what these men went through, and how history has come to understand them.
