'Celebrate from this time forward forever more' - John Adams
On July 4, 1776, the colonies then making up America declared independence from the kingdom of Great Britain. So the annual 'Fourth of July' holiday is probably the most important celebration of the year for most people in the United States,
John Adams was the second president of the United States and one of the founding fathers of its independence.
At the time he wrote to his wife, Abigail, saying that Independence Day would be the most memorable day in America.
He said that it should be celebrated with lots of parades and ceremonies - shows, games, different sports, bells and bonfires.
Independence Day is a national holiday and Americans celebrate it in true patriotic spirit. Because it's summer, most of the events take place outdoors.
