Beginning
Native Americans mined gold and traded it with
the Spanish Conquistadors in Florida, sent to "Get gold, humanely if you can, but all hazards, get
gold," by King Ferdinand of Spain.

California's Gold Discovery and The Gold Rush

In 1848, James W.
Marshall, a carpenter from New Jersey, discovered gold in the American River
while building his sawmill. This began The Gold Rush of 1849. Prospectors
flocked to California, risking their lives hiking across the Isthmus of
Panama (the Panama Canal hadn't been built yet), traveling by wagon train, and
sailing around Cape Horn. These miners are known as "The Forty
Niners".
The Gold Rush triggered the statehood
of California on September 9, 1850, and the huge westward U.S. expansion.
By 1849, 40,000 settlers had come by boat, and 6,000 wagons carrying thousands
more across the California Trail. Although the $2,000,000,000 gold mining
industry peaked by 1852, heavy settlement continued.

Comstock Lode Discovered

This enormous gold and silver strike brought even more people and prominence to the western territories. Once part of
California, the territory including the Comstock Lode area was made the state of
Nevada during the U.S. Civil
War. Its riches paid for the North's victory over the South, and assured the
future of the United States of America.
This strike, also, guaranteed an end to Native Americans' way of life,
who were forced onto small reservations of less desirable land.

1861-1865 Civil War

When 11 Southern States seceded
from the Union, the American Civil War began. It's hard to
imagine what
our lives would be like if the Confederate states had won the war. Who knows?
What we do know is that the Southern States did not have the wealth of natural
mineral resources that the North did. Much of the Union's war effort was
financed by The Comstock Lode. Supported by the many deposits of iron ore, lead
and coal, the North had a big advantage over the South. With a total of 617,528
dead, the Civil War stands as the bloodiest, costliest war in American history.

First Transcontinental Railroad

The
high rate of expansion, and gold and silver strikes in the Western Territories
prompted the construction of the first U.S. transcontinental railroad. The Union
Pacific Railroad building West
from Omaha, Nebraska and the Central Pacific
Railroad , building East from
Sacramento, California, joined in Promontory, Utah
on May 10th, 1869. This event provided fast and safer transportation from
East to West, and unified Americans from coast to coast.

1884 First
Skyscraper
The Home
Insurance Building , the world's first skyscraper, was designed and built in Chicago, Illinois by engineer William Le Baron Jenny. The 10-story-tall
structure began the use of steel-beam construction. Mostly, used only in America
until the turn of the century, steel-beam construction changed the steel
industry forever. American I-beam standards and steel construction materials
would be used worldwide. Now, many more people could live in as smaller area of
the city.
In 1889, the Otis electric elevator, also made of
steel construction, started a building boom of superstructures standing taller
than fifty stories within 10 years. Today, countries compete with eachother for
the "World's Tallest Building" title.

First Powered Airplane
Wilbur and Orville Wright made and flew the
world's first powered airplane called the "Flyer 1," (or the
"Kitty Hawk,") at Kill Devil Hills, North Carolina on the morning of

U.S. Entered World War I
By the time the United States entered World War
I, after German submarines sank three U.S. merchant ships, the Allied Forces in
Europe had already been fighting the war for years. U.S. supplies, loans and
troops supported the allied victory. By the end of the war, the United States had
loaned the Allies $7,000,000,000. Over 1,000,000 U.S. troops served in
Europe.

U.S. Entered World War II
By the time the United States
entered World War II, after Japanese forces attacked two American Naval bases,
in Pearl Harbor, Hawaii and Clark Field in the Philippines. The Allied Forces
had been fighting the war for years.
U.S. supplies, loans and troops supported the allied victory.
President Franklin D. Roosevelt closed all U.S. gold mines, so that mining
would produce only the minerals needed for war.
During this war, the race for atomic weapons took place. The United
States' , Manhattan Project,
successfully developed the world's first atomic bomb. After Japan refused to
surrender, President Harry S. Truman ordered it to be dropped on Hiroshima,
Japan, August 6, 1945. Still refusing surrender, Nagasaki, Japan was bombed on
August 9, 1945. Japan surrendered on August 14, 1945.
This was the beginning of the nuclear age.

ENIAC (Electronic Numerical Integrator
And Computer), the world's first electronic computer was activated February 14, 1946
at the University of Pennsylvania in Philadelphia, Pennsylvania. Built with over
17,000 electronic vacuum tubes, ENIAC could make mathematical calculations up to
1,000 times faster than mechanical computers. Funded by the United States
Military, ENIAC was the beginning of the computer industry.

1957
Alaska's oil deposits discovered
Alaska was purchased in 1867 from Russia by
Secretary of State William H. Seward for the United States. And though the
purchase of $7,200,000 made the cost per acre less than $1, it was not considered a
good purchase. It was so far away, so cold, and harsh, and communication was so
slow, that hardly anyone saw its value. Alaska's purchase became known as
"The Seward Folly".
The huge oil deposits discovered in 1957 led to the statehood of Alaska on
January 3, 1959. This made the United States 20% bigger, because Alaska is twice
as big as Texas.
