What is the author's purpose in the biography, Why Not, Lafayette?

It is Fritz's purpose to show how Lafayette's connection to America influenced his life, thus the book emphasizes the two periods in America and Lafayette's efforts to secure civil rights for the people of France. His tireless campaigns for the rule of fair and just laws are tied to his experiences in the United States, where he saw examples of ordinary people ruling themselves successfully. His trip as the guest of the United States serves not only to show how much Americans loved him and how much he loved them, but also to show how his gallantry, care for his troops, and his determined courage in the defense of the rights of others inspired Americans.
