Americans celebrate the Fourth of July as American Independence Day commemorating the day the United States of America was born when 13 colonies declared their independence from Great Britain.

People celebrate the National Holiday with hot dogs, beer, barbecues and most importantly, with the magnificent fireworks that light up the sky during the night.

Celebrations apart, how many people know the history behind this momentous day?

Here are some interesting facts that IBTimes UK has put together on the origin of the Fourth of July.

Origin and History

On 4 July 1776, 13 colonies announced their separation from Great Britain by adopting the Declaration of Independence.

The Second Continental Congress (comprising the group of 13 colonies) declared the American colonies free and independent, with John Hancock, the president of the Second Continental Congress, putting his stylish signature on the Declaration.

The Declaration of Independence, which asserts "all Men are created equal," was drafted by a committee comprising Benjamin Franklin, John Adams, Thomas Jefferson, Roger Sherman, and Robert R Livingston.

John Adams, in a letter to Abigail Adams, described people in Philadelphia spontaneously celebrating the first anniversary of American independence.

However, the country got its actual independence only on 3 September, 1783 when Great Britain formally abandoned all claims to the United States and signed the Treaty of Paris.

Independence Day celebrations became common only after the War of 1812.

On June 28, 1870, Congress passed a law making 4 July a federal holiday. People from far and near congregated to celebrate the day.

It was only in the 1870s, almost a century after the first Declaration of Independence, that Fourth of July became the most important secular holiday on the country's calendar.

Interesting Facts About Independence Day

2. Thomas Jefferson, one of the founding fathers of America, died exactly 50 years after the signing of the Declaration - on 4 July, 1826. In a strange coincidence, John Adams, another founding father too died on the same day as Jefferson.

4. According to the American Pyrotechnics Association's estimation, more than 14,000 firework displays illuminate the skies of the country on 4 July.

5. The firework industry earns about 75% of its revenue on this day and spends almost 11 months a year planning the holiday sale.
