The British colonization of the Americas (including colonization by both the English and the Scots) began in 1607 in Jamestown, Virginia, and reached its peak when colonies had been established throughout the Americas. The English, and later the British, were among the most important colonizers of the Americas, and their American empire came to rival the Spanish American colonies in military and economic might.
Three types of colonies were established in the English overseas possessions in America of the 17th century and continued into the British Empire at the height of its power in the 17th century. These were charter colonies, proprietary colonies, and royal colonies. A group of 13 British American colonies collectively broke from the British Empire in the 1770s through a successful revolution, establishing the modern United States. After the end of the Napoleonic Wars (1803–15), the remaining British territories in North America were slowly granted more responsible government. In 1838 the Durham Report recommended full responsible government for Canada, but this was not fully implemented for another decade. Eventually, with the Confederation of Canada, the Canadian colonies were granted significant autonomy and became a self-governing Dominion in 1867. Other colonies in the Americas followed at a much slower pace. In this way, two countries in North America, ten in the Caribbean, and one in South America have received their independence from Great Britain or the later United Kingdom. All of these, except the United States, are members of the Commonwealth of Nations and nine are Commonwealth realms. The eight current British overseas territories in the Americas have varying degrees of self-government.
Answer:
For the first, I would say being poorly represented.
For the second, ignorance and morals.
Explanation:
A lot of people have been raised to demand a change when they see injustices, some might go at it in a violent way, others might approach it in a more peaceful way. One thing you have to know about making big decisions, is that you will never please everyone. Someone is always going to be mad. It depends on their moral values as people. If you saw something that you thought was morally wrong, you would be upset too. They have tried peaceful protests and weren't heard, now they choose to incite violence because they have a voice and are represented in the media that way.
It all leads down to morals. The media says that if you aren't for it, you're automatically against it. If something the media does or activists do doesn't allign with people's morals, they choose the complete opposite because they think that's their only option.
Japan needed abundant natural resources to support both its population and its empire, something that the country lacked.
