The next part is about his entry into Missouri politics as a county judge, getting elected as a Democratic senator, and becoming vice president. The first part discusses the future president’s ancestors, his early years on a farm, his schooling, and his experience in World War I. Each part focuses on a major period in the subject’s life. Truman comprises six parts and 18 chapters.

In his view, Truman personified an American by-the-bootstraps ideal thanks to his hard work, honesty, integrity, and resilience. One of McCullough’s main themes is Truman’s rise from a relatively humble background-as compared to privileged East Coast politicians-to the highest levels of power.

McCullough begins in the antebellum era tracing the migration of Truman’s ancestors to western Missouri. The book traces Truman’s life from his farming ancestors to his political career as senator, vice president, and president.
