in the South. The beginning of the Civil War was
marked by an attack by the Confederate Army on
Fort Sumter in Charleston, South Carolina, on
April 12, 1861.
Also in April 1861, Lincoln suspended the writ
of habeas corpus, a fundamental right that
was derived from English common law and was
incorporated into Article I of the U.S. Con-
stitution. The writ requires that public offi cials
bring all prisoners before the court to present
their reason(s) for detainment. Lincoln’s suspen-
sion of the writ instigated an unprecedented use
of presidential power. Prior to this, only a select
few presidents used the latitude of the offi ce to
make decisions that were generally considered
beyond the scope of what the Founding Fathers
had likely intended for the chief executive. (Prior
examples, would be George Washington’s issu-
ance of the Proclamation of Neutrality during the
war between France and Britain after the French
Revolution, Thomas Jefferson’s use of presiden-
tial power to conduct the Louisiana Purchase,
and Andrew Jackson’s decision to remove federal
funds from the national bank and his dismissal of
the treasury secretary from his administration.)
Even though the nation was torn apart by civil
war, the U.S. Supreme Court ruled in E
X PARTE
MILLIGAN, 4 Wallace 2 (1866), that the president
did not have the authority to suspend the writ.
This decision set a precedent under which presi-
dents were afforded extensive powers, particularly
in times of crisis, but not to the extent that they
could suspend fundamental rights provided
for in the U.S. Constitution. Further, the case rein-
forced the power of the Court to check the execu-
tive branch and curtail presidential actions that are
perceived as exceeding the boundaries of executive
authority. This Civil War–era case precedent was
a poignant consideration when the U.S. Supreme
Court later became a check on several 20th-cen-
tury presidents, most notably Franklin D. Roos-
evelt, Harry Truman, and Richard M. Nixon.
As the Civil War continued, the number who
were either wounded and/or died grew to stagger-
ing numbers on both sides. Lincoln’s antislavery
stance intensified during the war, and in June
1862, he signed a law that banned slavery in the
United States. The Emancipation Proclamation,
issued by Lincoln on January 1, 1863, proclaimed
that all slaves living on Confederate soil were free.
Lincoln delivered the Gettysburg Address, one of
the more famous speeches in American history,
on November 19, 1863. He won a second term in
offi ce in the presidential election of 1864. Shortly
thereafter, the Confederate Army had endured
casualties so great that it was forced to surrender
on April 9, 1865. General Robert E. Lee surren-
dered to General Ulysses S. Grant at Appomattox
Courthouse, in Virginia. On April 11, Lincoln
spoke publicly for the fi nal time. He was assassi-
nated on April 14, 1865, by John Wilkes Booth,
while attending a play in Washington, D.C.
Despite the divisive nature of the Civil
War, the nation reunited and the Constitution
remained intact, although not without amend-
ments. Lincoln’s legacy, the changing political cul-
ture of the nation, and the Reconstruction policies
after the war all became catalysts for change. The
post–Civil War era introduced a series of constitu-
tional amendments in the Reconstruction era that
were ratifi ed to promote universal suffrage and
human rights. For instance, ratifi ed on Decem-
ber 6, 1865, the Thirteenth Amendment was
designed to end slavery in the United States and
any associated territories falling under its jurisdic-
tion. The Fourteenth Amendment, ratifi ed on
July 9, 1868, provided that freed slaves are U.S.
citizens. It also guarantees that citizens will be
afforded “equal protection of the laws” and
prohibits states from depriving “any person of life,
liberty, or property, without due process of law.”
The Fifteenth Amendment was the last of the
post–Civil War era. Ratifi ed on February 3, 1870,
the Fifteenth Amendment extended voting rights
to all citizens, irrespective of “race, color, or previ-
ous condition of servitude.”
These amendments did not guarantee that
such safeguards would be aggressively enforced,
and their implementation in U.S. society has often
been a slow and incremental process. Opposition
against efforts to end racial and prejudicial behav-
ior was apparent, particularly in the South where
an agricultural economy had traditionally relied
extensively on slave labor. It was not until the mid-
