America will celebrate its 250th birthday in July.
In 1776, the Declaration of Independence asserted that governments derive “their just powers from the consent of the governed” and challenged centuries of inherited power and monarchy. The American founding drew from decades of debate about liberty, rights, power, and the responsibilities of a free people, launching what the Founders saw as a new experiment in self-government.
Lexandria’s eTextbook, The American Experiment: 250 Years of Enduring Principles, traces the intellectual roots of the American founding and examines the ideas and institutions that continue to shape civic life today.
250 years later, Americans still carry that experiment forward.
