Colonization and causes of the revolutionary war

Causes of the Revolutionary War

The American people were strongly independent. They wanted to do things for themselves. Great Britain was a long way away. The American people didn't want people an ocean away telling them how to live their lives.
The British government decided to make the American colonies pay a large share of the war debt from the French and Indian War.
Through the Sugar Act, Stamp Act, and other taxes, the British tried to collect taxes that the American people considered harsh.
The American people also thought that they should be able to send their own people to Britain's Parliament or at least vote for Britain's lawmakers.
The combination of the harsh taxes and the lack of an American voice in Parliament gave rise to the famous phrase "taxation without representation."
Patrick Henry, Thomas Paine, and others called for an independent America, colonies free from British rule and interference.
Americans started stockpiling guns and ammunition in violation of British laws. Their defense of such a stockpile led to the shots fired at Lexington and Concord and the beginning of the Revolutionary War.

They wanted the Japanese to open their ports to American trade and they organised the Perry expedition

Explanation:

The Perry Expedition was a diplomatic expedition to Bakumatsu period Japan, involving two separate trips by warships of the United States Navy, which took place during 1853–54. The goals of this expedition included exploration, surveying, and the establishment of diplomatic relations and negotiation of trade agreements with various nations of the region; opening contact with the government of Japan was considered a top priority of the expedition, and was one of the key reasons for its inception.

The expedition was commanded by Commodore Matthew Calbraith Perry, under orders from American President Millard Fillmore.

Perry’s primary goal was to force an end to Japan’s 220-year-old policy of isolation and to open Japanese ports to American trade, through the use of gunboat diplomacy if necessary. The Perry Expedition led directly to the establishment of diplomatic relations between Japan and the western "Great Powers", and eventually to the collapse of the ruling Tokugawa shogunate.
