How definitions of childhood in early America codified social hierarchies and remain with us todayAs of 2025, in the United States an eleven-year-old child can be charged with a federal crime while in many states it's illegal to leave a twelve-year-old home alone. Twenty-six states allow children younger than sixteen to marry while the legal drinking age remains twenty-one. Are these age-based laws really protecting children, and if not, why do they exist? Holly White uncovers the answers to these questions through a history of America's first age-based laws.Analyzing trial records, newspapers, personal letters and diaries, as well as legal statutes from the founding era to the Civil War, White shows how restrictive age-based laws were implemented to benefit those who already held power. Over time, these new laws-coming out of child murder and rape trials as well as guardianship and underage marriage disputes-increasingly circumscribed the rights of young Americans in the early republic. As White shows, race, class, status, and gender influenced who came to benefit from the label of "e;child"e; in post-revolutionary America. In so doing, Constructing American Childhood explains why Americans continue to be guided by the age-based legal definitions of childhood and adulthood of our past.
