Territorial expansion followed with the Louisiana purchase in 1803; Texas; California and the south-west following the Mexican -American war from 1846 to 1848.

Success in the war and the California Gold Rush in 1848 helped to open up the Wild West and the Pacific coast. The spread of the railway network and the huge immigration from Europe began to fill the Great Plain.

From 1812 till 1861 the Mississippi Valley and the great Lakes region were populated with settlers. The mid 19th century there were constant political crisis over slavery (abolished 1865) and States Rights. It led to the American Civil War from 1861 to 1865.

The last decades of the 19th century saw the purchase of Alaska and regaining the Spanish colonies after the Spanish American War in 1898.

In the 20th century the USA has become a world power. It got involved in the First World War and Second World War. At the end of the Second World War it dropped atom bombs at Japan's Hiroshima and Nagasaki.

Since it had played an active role in "world policing" with the UN headquarters based in New York, USA.

In the determination (or cover) to prevent the spread of communism it fought in the Korean War - 1950-53 and Vietnam War 1964-75 and supported anti-communism regimes especially in Latin America.

But the USA also supported the Khmer Rouge, Papa Dog and Baby Dog, to name just a few, which is still incredible. Those regimes  were one of the worst blood bath.

During the 1970 and 1980 with the Cold War, between the West and East block, easing off  the USA started an arms reduction with the Soviet Union.

The USA was also involved in the Gulf War during 1991.

Back home the USA faced many crisis. The severe depression and followed by the Stock Market Crash in 1929; a campaign of civil troubles which led to the Civil Right Act in 1964. The assassination of John F Kennedy in 1963; the programme of the first Moon landing in 1969;  the Watergate scandal of Richard Nixon and his resignation in 1974.

During the last decades the USA invaded countries and was involved in a number of illegal wars including the UK.  Such as Laos, Cambodia, Lebanon, Libya, Afghanistan, Iraq and lately Syria all under the cover of being ruled by dictators and trying introducing democracy. However, all these countries are divided and in a complete mess.
