After the French Revolution era, the Directory was overthrown by Napoleon Bonaparte on 9 November 1799. Following this, Napoleon Bonaparte became an absolute ruler of France and in 1804 he was granted the title of Emperor of the French. Under his government, France was involved in several wars -known as the Napoleonic wars- against European powers where he wanted to export the revolution and extend his dominion.
Within France class struggles continued, as the government started persecuting the Monarchists, who wanted to re-establish the old monarchy and the Republicans who were against Napoleon and wanted to re-establish the Republic. Class conflicts continued in France for many decades after Napoleon was overthrown in 1815.
