The 18th and 19th centuries formed a transcendental historical period, as it transitioned from the Modern Age to the Contemporary Age. This change was brought about by the French Revolution of 1789, an event that had such an impact that it transformed the society subjected to the Old Regime into a completely different one that would fight for its rights. In Spain, this historical period was immersed in the political, intellectual, and cultural framework of the Enlightenment, where scholars emerged who advocated reason and science as the fundamental tools for achieving human progress. On the other hand, the country experienced the conflict of the War of Independence, which would bring devastating consequences to our nation.
