Answer:

Reason for settlement:

Like many of the early American colonies, the Massachusetts Bay Colony, founded in 1630, has its roots in the search for religious freedom. The Puritans of England came to Massachusetts in hopes of living free from persecution for their religious beliefs.

Geography and climate:

The Massachusetts Colony was classified as one of the New England Colonies. Geography & Climate: Mountains, trees, rivers but poor rocky soil that was difficult to farm and unsuitable for crops. Mild, short summers and long, cold winters.

I can't remember what the religions were but i think you can look it up ^^

Settlers

The first settlers in Massachusetts were the Pilgrims who established Plymouth Colony in 1620 and developed friendly relations with the Wampanoag people. This was the second permanent English colony in America following Jamestown Colony.

Economy:

The early colonial economy of Massachusetts was primarily based on agriculture. ... By 1641, the characteristic activities of Massachusetts—fishing, shipping and trading—were well underway. Deep, sheltered harbors and a long coastline, together with abundant fish and timber, fostered the emerging maritime economy.

goverment:

The Massachusetts Bay Colony was a charter colony. This meant that the administration of the colony was elected by the colonists and the colony was allowed to self-govern, as long as its laws aligned with those of England.

(BRAINLIEST FOR BEST ANSWER) Why did the Tea Act anger the colonists? Explain how the tax on tea affected merchants and their customers.

Answers

Answer:

The Tea Act angered the colonists because the Tea Act was passed by the English Parliament rather than their own governments and the Tea Act had granted the British East India Tea Company to create a monopoly. They believed it violated their rights as citizens.

It angered them because it favored a British company over colonial merchants. They could only buy from the British East India company and were no longer allowed to buy any tea they wanted.

Why did the English colonies have a difficult time seeing themselves as one nation?

Answers

Because they where still ruled by the king of Britain.

The English colonies had a difficult time seeing themselves as one nation because they acted as the independent republics rather than the United States.

What were Colony?

The Colony refers to the region where the native people were ruled by the dominating state who came to another country in order to trade and acquire the political power.

They were the immigrants to a new area with the support of the government. They are also referred as the settlers in the new region.

Therefore, it can be concluded that Because they operated more like autonomous republics than the United States, the English colonies had a hard time understanding their unity. Each set out on its own course, which made achieving unification in the end quite challenging.
