“ Happy Birthday, America! “

July 4th, or Independence Day, is the most important American holiday. It`s the birthday of the United States of America. On this day, in 1776, America signed the Declaration of Independence and started the fight for freedom from British rule.
Before 1767, the King of England, George 3, ruled the thirteen colonies in America. The colonists were tired of the taxes that George 3 imposed on them. In 1776, the British Government placed new taxes on tea and paper that the colonists imported from abroad. The colonists got angry and refused to pay. George 3 sent soldiers to keep order.
In 1773, a group of colonists dressed up as Indians threw 342 chests of tea belonging to the East India Company into the waters of Boston harbour. King George didn`t think it was funny. His reply to this “Boston tea party” was a set of laws to punish the colonists. Boston harbour was closed until the tea was paid for. More soldiers were sent there to keep order. The war of Independence began.
On July 4, 1776, the colonists declared their independence from Britain. Led by Thomas Jefferson, the representatives of all thirteen colonies met in Philadelphia to sign the Declaration. A large part of it was written by Jefferson himself. The document stated that the colonies were now “free and independent states” and officially named them the United States of America. It also said that all men had a natural right to “life, liberty, the pursuit of happiness”. People celebrated the birth of a new nation.
But the War of Independence dragged on until 1783 when the colonists finally won. The head of the Revolutionary Army was George Washington, who later became the first president of America.
