The document summarizes key events leading up to the American Civil War between 1840-1863. Tensions grew between the northern and southern states over the issues of slavery and states' rights. The Mexican-American War and Compromise of 1850 temporarily eased tensions but did not resolve the core issues. The Dred Scott decision and election of Abraham Lincoln further polarized the nation. Several southern states seceded and formed the Confederate States of America. After the Confederate attack on Fort Sumter, the Civil War began in 1861. Major battles like Bull Run, Antietam, and Gettysburg resulted in high casualties as the Union fought to preserve the United States and abolish slavery.

2. Imminent Crisis
Until the 1840 decade, strains between
North and South remain relatively quiet.
This conflict less situation gave hope to a
peacefully reconciliation between this two
regions. But new problems emerged with
the slavery expansion.
From the North arrived the powerful
Abolitionist Movement, while, in South,
appeared a new defense to the slavery
system and the way of life. Irreconcilable
proposals that, at the end, tore the Union.
3. The Mexican War
For years, United States ambitioned the fertile and
wasted territories of North Mexico. In 1846,
President Polk intended vainly to bribe Mexican
government, so he sent Gral. Taylor to cross Nueces
River.
In spite of the opposition to the war, the invasion
continued and US Army took Monterrey, while Gral
Kearny was sent to New Mexico and California.
Finally, another army lead by Gral.Scott advanced
through Mexico卒s valley and won Molino del Rey,
Chapultepec and Churubusco.
In 1848, with the Guadalupe Hidalgo treaty, Mexico
and the US signed an agreement.

5. Slavery and new territories
During Mexican War, David Wilmot proposed
an amendment whereby slavery were
forbidden in the conquered territories.
Southern militants argued that all Americans
had the same rights in all territories.
New president Taylor, believed that each state
may solve this problem. But the debate about
fugitive slaves and the fear of southern states
of an unbalanced Congress, knocked down
this idea.
Tempers flared dangerously, even a lot of
moderate southern leaders spoke about
separation.
6. The 1850 Compromise
Involved in that crisis,
moderates and unionist spent
the winter of 1849 planning a
great Compromise.
After six months of
deliberations, the Old and
romantic Guard didn卒t reach
an agreement, so new faces
like Jefferson Davis and
Stephen Douglas took the
leadership understanding the
importance of flexibility and
pragmatic policies.
This Compromise wasn卒t a
product of a common national
ideals but a triumph of
personal interest.

controversial ruling of history.
Dred Scott was a slave from
Missouri bought by a surgeon who
took him until Illinois and Wisconsin
(where slavery was forbidden).
When the surgeon passed away,
Scott demanded his freedom
arguing that his staying in a free
territory makes him a free man.
The brother of the widow claimed
the possession, arguing that Scott
hadn卒t legal support because he
was a property, not a citizen. It was
a hard defeat for abolitionist and
northern.
9. The election of 1860
This election had the most serious consequences in
US History.
The election focused in the candidates of Republican
party, Abraham Lincoln; and Stephen Douglas, from
Democrat party of the north.
Lincoln had a great political magnetism because his
orator fame.
Lincoln won the election, but Republicans didnt
achieved the Congress majority. So, that constituted
the final sign for many white southern about his
allegiance with the Union.
Few week after Lincoln's victory, started the process
of secession.
10. The Secession
At the end of 1860, the laces that remained together the
Union started to tear.
South Carolina, home of southern separatism, was the
first state to secede in December 1860. Later, in January,
Mississippi, Florida, Alabama, Georgia Louisiana and
Texas continued.
In February of 1861, in Montgomery, Alabama, they
founded a new nation: The Confederate States of
America.
Secessionist took federal buildings and siege Fort Sumter.
When President Lincoln said that every act of violence to
preserve the secession would be consider as rebellion,
Confederate forces bomb Fort Sumter.
Civil War had begun.
11. The sides
In case of war, material
advantages were with the
Union. Their population
doubles South, had an
advanced industrial system
and were able to manufacture
their own war supplies.
The south fought a defensive
war in their land and with
local help. The Confederate
disposition to war were firm,
while in North, were
frustration and division. One
Rebel victory in one of the
crucial moments would be
decisive.
13. Union Leadership
The most important of the
military commanders was
Lincoln, with a little
experience in militia.
From 1861 to 1864 Lincoln
tried to find a chief
commander do lead the
Union army, first he
appealed to Winfield Scott,
but he resigned; George
McClellan, a proud and
arrogant General that
never found wanting.
Until March 1864, Lincoln
found a trusty General who
share his way of fighting
this war: Ulysses S. Grant.
14. Afro-Americans and the
Union
186 000 emancipated
Negroes served as soldiers,
sailors and workers as well
as an important number of
free North Afros.
During the first months these
men were excluded of army,
but when Lincoln pronounced
the Emancipation
Proclamation, the number of
volunteers rise rapidly.
Most Negroes did humble
task, but some were
organized as combat units,
the most prominent were the
54th Massachusetts
Regiment .
16. Confederate Leadership
The South military
leadership was in hands
of President Davis, who
was a professional
soldier.
At the beginnings of
1862, Davis named
Gral. Robert E. Lee as
his principal military
counselor, but Davis
never shared the
strategic control.
In 1864, Davis deposed
Lee and named Gral.
Braxton Bragg.
17. The Emancipation policy
As the conflict got deeper, many northern
started to understand that emancipation
should be the main objective of the war.
Nothing less justify the huge sacrifice
demanded by it.
Lincoln assumed the leadership of this feeling
and in September 22th 1862, after Antietam
Battle, he used his extraordinary powers to
issue a warrant whereby all the slaves in the
Confederate states were free. In January 1st
1863, this Proclamation was sign.
After two centuries, legal slavery was no
longer in the United States.
19. War technology
Much of what happened
in the battlefield was the
result of new
technologies that
change the way of
making war.
The Civil War is also
called as the first
modern and total
war. However, this
conflict was something
different as others
before and set the tone
for future military
operations.
20. War technology
Two brand-new
technologies were vital
for the war course: Train
and telegraph.
Trains were important in
a war where you need
to transport millions of
soldiers and supplies.
However, they limited
the armies mobility.
The new U.S. Military
Telegraph Corp trained
and employed 1200
men that sent messages
that, in other time,
required days for being
received.
22. The first encounter: Bull
Run
Both armies faced each other in Manassas,
Virginia. Irving McDowell, with 30 000 Union
soldiers against a 29 000 Confederates lead
by P.G.T. Beauregard. Union commanders
though that if southern were defeated, the war
should be ended.
At the beginning, McDowell almost disbanded
Confederate forces, but they stopped, counter
attacked and surprised Union troops that tired
for the combat, panicked and broke ranks.
Disorganized retreat that was hampered by
civilians that came from the Capital with picnic
baskets to watch the battle as a country sport.
26. 1863 The decisive Year:
Gettysburg
Lee decided upon an invasion of the North. The invasion
would allow the Confederates to live off the bounty of the
rich Northern farms while giving war-ravaged Virginia a
much-needed rest. Lee's 72,000-man army could threaten
Philadelphia, Baltimore, and Washington, and possibly
strengthen the growing peace movement in the North.
The Union Army under Gral. Joseph Hooker (later
Meade), consisted of a combined strength of about
94,000 men.
Lee attacked in Cementery Ridge but failed, and the next
day intended a desperate attack in an Union well
defended hill, this attack is remembered as Pickett卒s
Charge.
After three days of battle and the lost of 1/3 of his army,
Lee withdrawal from the battlefield. Never the south were
able to threat seriously northern territory.
