In 1871, Montmartre was the site of beginning of the revolutionary uprising of the Paris Commune. During the Franco-Prussian War, the French army had stored a large number of cannon in a park at the top of the hill, near where the Basilica is today. On 18 March 1871, the soldiers from the French Army tried to remove the cannon from the hilltop. They were blocked by members of the politically-radicalised Paris National Guard, who captured and then killed two French army generals, and installed a revolutionary government that lasted two months. The heights of Montmartre were retaken by the French Army with heavy fighting at the end of May 1871, during what became known as "Bloody Week".
