There was also widespread political discontent. King Louis-Philippe of France was overthrown during the Revolution of 1848 and a republic was established. In 1870–71, Prussia defeated France in what became known as the Franco-Prussian War. The combination of natural and man-made disasters created an acute feeling of hopelessness in both France and Corsica. Hundreds of families fled Europe and immigrated to the Americas, including Puerto Rico. All of this came about when the Spanish Crown, after losing most of her possessions in the so-called "New World", was growing fearful of the possibility of losing her last two possessions, Cuba and Puerto Rico.
