In 1868, the Spanish queen Isabella II was deposed in the Glorious Revolution, leaving the country's throne vacant. When Prussia suggested the Hohenzollern candidate, Prince Leopold as successor, France vehemently objected. The matter evolved into a diplomatic scandal and in July 1870, France resolved to end it in a full-scale war. The conflict was quickly decided as Prussia, joined by forces of a pan-German alliance never gave up the tactical initiative. A series of victories in north-eastern France followed and another French army group was simultaneously encircled at Metz. A few weeks later, the French army contingent under Emperor Napoleon III's personal command was finally forced to capitulate in the fortress of Sedan. Napoleon was taken prisoner and a provisional government hastily proclaimed in Paris. The new government resolved to fight on and tried to reorganize the remaining armies while the Germans settled down to besiege Paris. The starving city surrendered in January 1871 and Jules Favre signed the surrender at Versailles. France was forced to pay indemnities of 5 billion francs and cede Alsace-Lorraine to Germany. This conclusion left the French national psyche deeply humiliated and further aggravated the French–German enmity.
