It gave them company-owned towns in which to live. Verified. I took the test.
The south improvement company in 1872 caused rockefeller able to monopolized around 90% of the oil market in North America.
The south improvement company largely increased the number of oil and railroad companies in southern states. Because of the increase in numbers, the market for oil and railroad companies became saturated. This lead many of his competitors to bankruptcy, which is why the competitors called it a conspiracy.
It was one of the first democratic governments in recorded history. Letting people vote on leaders was revolutionary at the time and did lead to things like the roman republic, the american revolution, and the french revolution. It lead to a lot of time being spent on the tragedy of being human or self aware. Which of course lead to things like maybe i deserve to have a say in the government.
Later when the Romans took over they looked at all the Greeks stuff and thought huh? maybe this is a good idea. And the rest of course is history.
Hope this helps
The use of good guy or bad guy for a person doesn't make much sense.
I'll just list some major facts about Columbus and let you make your own conclusions.
Christopher Columbus believed the world was round. Others during his time didn't believe so. Columbus also thought that the world was smaller than what it actually is, principally because North America and South America were not yet discovered. Columbus went to many people and asked them to fund him, and finally the King and Queen of Spain funded him. When Columbus reached the Americas, he treated the natives harshly. He took their wealth, such as gold, etc, and made the natives slaves. And he brought back the riches of the Caribbean to Spain. Columbus never knew that he had stumbled across an undiscovered land, and instead thought he had reached India, where he was originally going for, and so he called the natives "Indians."
Hope that helped :)
