Answer: Abraham Lincoln is generally considered the greatest president for his leadership during the American Civil War and his eloquence in speeches such as the Gettysburg Address. James Buchanan, Lincoln's predecessor, is generally considered the worst president for his leadership in the build-up to the Civil War.
Explanation:
The 24th Amendment prohibited poll taxes or other taxes as qualifications for voting.
Poll taxes had been a way states had discriminated against black voters, by using their lower income status and poll taxes as a way to prevent them from going to the polls. During the civil rights movement of the 1950s and 1960s, this was challenged. The 24th Amendment, ratified in 1964, said: "The right of citizens of the United States to vote in any primary or other election for President or Vice President for electors for President or Vice President, or for Senator or Representative in Congress, shall not be denied or abridged by the United States or any State by reason of failure to pay any poll tax or other tax," and added: "The Congress shall have power to enforce this article by appropriate legislation."
Some examples of this were the Fugitive Slave Act, Preston Brooks's attack on Charles Sumner, and the Dred Scott decision (the part of it which said that African Americans could never be citizens). None of these events tangibly hurt the North or the South.
Countries such as Spain, France and Portugal colonized the region. Although most of Latin America was colonized by Spain, the countries of Portugal and France also had major influences on the region. Due to war and disease, native populations were decimated.
