Martin Luther King fights for political rights                     
for black people in the USA. King went university                        
when he was fifteen. Win a scholarship gave him                         
the chance to go to a college in one of the northern state,                 
which black people had equal rights and were free to                        
live, study and working as they wished. All his life he                     
believed that it was right and necessarily to demand                        
changes in the society if people did not have their civil                       
rights. He believed that she could achieve that goal                        
by peaceful actions, not violence.
