How did the people of the french revolution overthrow the government?

I believe they beheaded Marie and King Louie. And they also tore down the biggest prison, brick by brick, as a symbol of their new freedom.

Everything started in 1789, when France was nearly bankruptcy. Thounsands of angry poor people decided to storm the Bastille prison - the symbol of the monarchy and old bad times. But it was only the beginning of the French Revolution. When France became a republic, in 1792,  people executed the king Louis XVI and his wife. The idea of revolution spread around the country, peasants were eliminating old authorities killing them by the guillotine.
