How did the presidency change from the time of George Washington to Abraham Lincoln?
Considering how some of the important presidents such as Washington, Adams, Jefferson, and Jackson used their powers as presidents to deal with major issues of their time.
We have limited space for a multi-faceted question like this, but I can get you started with some ideas to pursue.
Both Washington and Lincoln were in charge of politically and socially divided countries, but as time went on in the first eight decades of the United States under the Constitution, the power of the Presidency grew stronger.
Partly this was because the United States did as well, with a much greater area of land (31 states instead of 13), almost eight times as many people and a much larger economy by the time Abraham Lincoln was elected.
Another reason, though was the consistently pro-federal government rulings of the Supreme Court under John Marshall from 1801 - 1835, building a body of legal precedent that most often favored the power of Washington D.C. over that of the states.
