I guess I'll just write about people, since it'll be the fastest for me.
1. George Washington, the very first president of the United States of America. He was a great leader, and he helped bring an entire nation together with the help of his allies and supporters.
2. Frederick Douglass, a runaway slave and the man who most likely contributed to the Black Power movement the most. He gave powerful speeches everywhere, and thanks to that he helped make all black men and women free from slavery. Not equal, but they were free.
3. Rosa Parks. She boycotted against the way blacks were treated, and, probably the most memorable thing she did, she refused to sit in the back of a bus, where the blacks were forced to sit, and that brought more people to fight for black rights.
This is true.
The Commodore, as he was nicknamed, got his start with ferries and then expanded into steel and other investments.
Carnegie accumulated a lot of money and gave a lot of it away but was also fairly criticized as being a robber baron.
I think it's just the right thing to do.
