The March on Washington occurred August in the year 1963. The purpose of this action was to gather support for the passing of the Civil Rights act. About 250.000 people were a part of the march and it was during this ceremony that Martin Luther King Jr. delivered his famous I Have a Dream speech .
Maximilien Robespierre (1758-1794) was one of the leaders and orators of the French Revolution of 1789, best known for his involvement in the Reign of Terror that followed.
As a young man, he studied law and had a reputation for honesty and compassion. He sought to abolish the death penalty and refused to pronounce a required death sentence after becoming a judge.
But as the revolution approached, Robespierre became head of the powerful Jacobin Club, a radical group advocating exile or death for France's nobility. In 1792, after Paris mobs stormed the palace of the Tuileries and dethroned King Louis XVI and Queen Marie Antoinette, Robespierre helped organize the new revolutionary governing body, the Commune of Paris.
