Britain's American
colonies broke with the mother country in 1776 and were recognized
as the new nation of the United States of America following
the Treaty of Paris in 1783. During the 19th and 20th centuries,
37 new states were added to the original 13 as the nation
expanded across the North American continent and acquired
a number of overseas possessions. The two most traumatic experiences
in the nation's history were the Civil War (1861-65) and the
Great Depression of the 1930s. Buoyed by victories in World
Wars I and II and the end of the Cold War in 1991, the US
remains the world's most powerful nation state. The economy
is marked by steady growth, low unemployment and inflation,
and rapid advances in technology.
The United States of America is a federal democratic republic
situated primarily in central North America. It comprises
50 states and one federal district, and has several territories.
It is also referred to, with varying formality, as the United
States, the U.S., the U.S.A., the States, or simply and most
commonly, America.
The official founding date of the United States is July 4,
1776, when the Second Continental Congress—representing
thirteen British colonies—adopted the Declaration of
Independence. However, the structure of the government was
profoundly changed in 1788, when the states replaced the Articles
of Confederation with the United States Constitution. The
date on which each of the fifty states adopted the Constitution
is typically regarded as the date that state "entered
the Union" (became part of the United States). Since
the mid-20th century, following World War II in alliance with
Great Britain, the United States has emerged as the dominant
global influence in economic, political, military, scientific,
technological, and cultural affairs.

Anthem
United
States
The United States' National Anthem
In
1814, Francis Scott Key wrote new words for a well-known drinking
song, "To Anacreon in Heaven," to celebrate America's
recent victory over the British. However, only in 1931, following
a twenty-year effort during which more than forty bills and
joint resolutions were introduced in Congress, was a law finally
signed proclaiming "The Star Spangled Banner" to
be the national anthem of the United States.
Oh, say can you see, by the dawn's early light,
What so proudly we hailed at the twilight's last gleaming?
Whose broad stripes and bright stars, through the perilous
fight,
O'er the ramparts we watched, were so gallantly streaming?
And the rockets' red glare, the bombs bursting in air,
Gave proof through the night that our flag was still there.
O say, does that star-spangled banner yet wave
O'er the land of the free and the home of the brave?
On the shore, dimly seen through the mists of
the deep,
Where the foe's haughty host in dread silence reposes,
What is that which the breeze, o'er the towering steep,
As it fitfully blows, now conceals, now discloses?
Now it catches the gleam of the morning's first beam,
In full glory reflected now shines on the stream:
'Tis the star-spangled banner! O long may it wave
O'er the land of the free and the home of the brave.
And where is that band who so vauntingly swore
That the havoc of war and the battle's confusion
A home and a country should leave us no more?
Their blood has wiped out their foul footstep's pollution.
No refuge could save the hireling and slave
From the terror of flight, or the gloom of the grave:
And the star-spangled banner in triumph doth wave
O'er the land of the free and the home of the brave.
Oh! thus be it ever, when freemen shall stand
Between their loved homes and the war's desolation!
Blest with victory and peace, may the heaven-rescued land
Praise the Power that hath made and preserved us a nation.
Then conquer we must, for our cause it is just,
And this be our motto: "In God is our trust."
And the star-spangled banner forever shall wave
O'er the land of the free and the home of the brave!
Economy
United States
Economy - overview:
The US has the
largest and most technologically powerful economy in the world,
with a per capita GDP of $40,100. In this market-oriented economy,
private individuals and business firms make most of the decisions,
and the federal and state governments buy needed goods and services
predominantly in the private marketplace. US business firms
enjoy considerably greater flexibility than their counterparts
in Western Europe and Japan in decisions to expand capital plant,
to lay off surplus workers, and to develop new products. At
the same time, they face higher barriers to entry in their rivals'
home markets than the barriers to entry of foreign firms in
US markets. US firms are at or near the forefront in technological
advances, especially in computers and in medical, aerospace,
and military equipment; their advantage has narrowed since the
end of World War II. The onrush of technology largely explains
the gradual development of a "two-tier labor market" in which
those at the bottom lack the education and the professional/technical
skills of those at the top and, more and more, fail to get comparable
pay raises, health insurance coverage, and other benefits. Since
1975, practically all the gains in household income have gone
to the top 20% of households. The response to the terrorist
attacks of 11 September 2001 showed the remarkable resilience
of the economy. The war in March/April 2003 between a US-led
coalition and Iraq, and the subsequent occupation of Iraq, required
major shifts in national resources to the military. The rise
in GDP in 2004 was undergirded by substantial gains in labor
productivity. The economy suffered from a sharp increase in
energy prices in the second half of 2004. Long-term problems
include inadequate investment in economic infrastructure, rapidly
rising medical and pension costs of an aging population, sizable
trade and budget deficits, and stagnation of family income in
the lower economic groups.
