If you can go back in History you may try Benjamin Franklin. Although he was never a president he had a lot of influence in drafting the constitution and getting France’s support durring the revolutionary war.

Margarat Thatcher the first female Prime Minister of England. Now that would be a good report. And it would have relevance to our current times with Hillary looking like getting the nomination for Democrat Party.

One of the more recent world leaders would be Newt Gingrich. He led the Republican Party to victory in the congressional elections of 1994. And they seemed to be doing pretty good until he resigned after getting busted for cheating on his wife. Since he left well you seen what happened to the Republicans.

Harriet Tubman and the Underground Railroad, she helped lead many slaves to freedom.

Thurgood Marshal the first black man on the Supreme Court.

I do hope those were some usefull ideas.

The whole Live Aid and Band Aid thing is really interesting and not too long to write about.
