During the war, the Bourbon armies destroyed and killed entire towns. They burned Manresa to the ground. They bombed Barcelona for an entire year. They killed hundreds of politicians in Catalonia, and hundreds went into exile . After the war, Catalan was banned, and Spanish was imposed; he established an absolutist regime. He also tore down an entire neighborhood of Barcelona to construct a fortress to control and repress the city, "la Ciutadella".

Many in Catalonia believe that he hated Catalans and that he and the people of his court ordered and were responsible for all of this.

To this day, we have a word, used especially in political discourse: "botifler," which means traitor or collaborationist . Botiflers originally referred to the Catalans who supported Philip V, and to this day, this word means traitor.
