For my history homework i need to research someone historically significant but i have no idea who to write about. any ideas? ♥

Depends on what type of event you want to write about. 

William Shakespeare - English poet, writer

Karl Marx - father of Communism

Wolfgang Amadeus Mozart - composer

Martin Luther King - activist/leader of Civil Rights Movement

Christopher Columbus - legendary Italian explorer 

Ulysses S. Grant - part of the victory in the American Civil War w/ Lincoln

Overall, depends on what you want to write about. If you are allowed to write about anybody significant in our history, look through some of the options and just pick one that gets you interested. The more interested, the more you'll want to write.
