In the United States, ours is a government of the people, by the people, for the people, according to Lincoln's famous Gettysburg Address. But how did the federal and state branches of government get to be so complex--and why did a separation of powers evolve in the first place? Aiming to demystify many of these issues in terms modern students can understand, By the People examines the history of American government, making use of maps, charts, call-outs, and other infographic-packed features to spotlight memorable facts and bolster the surrounding narrative. We the People sidebars provide biographical sketches of key figures, from senators and presidents to justices and mayors. A historical survey of the presidential cabinet, from its beginnings to current structure, including its executive role and influential members such as Salmon P. Chase.
