In 1843 there was a military uprising against the Espartero Regency. Colonel Prim takes Reus, but is forced to capitulate to avoid suffering for the civilian population; However, Narváez and Serrano prevailed in the rest of Spain, and Prim was named brigadier and obtained the title of Count of Reus, beginning a rapid political career. After being unjustly implicated in the attempted poisoning of Naváez, he is exiled, but after the attack on Ceuta, the government declares war on Morocco and rehabilitates Prim, who achieves a decisive victory in the battle of Castillejos. After the Mexican campaign, he returns to Spain and conspires against the moderate government, being exiled to London. In 1868, together with General Serrano and Admiral Topete, he commanded the September Revolution and was named President of the Government, being forced to use forceful measures that earned him the hatred of the Republicans. Finally, on December 27, 1870, after getting the Cortes to appoint Amadeo of Savoy as the new king of Spain, he suffered an attack on Turco Street, dying three days later.
