In this sweeping political reflection, former Spanish prime minister José María Aznar charts the transformation of Spain’s centre–right from the embattled Alianza Popular to a refounded, governing Partido Popular. Framing his account within a broader critique of factionalism, populism and the erosion of democratic legitimacy, Aznar explores the philosophical underpinnings of party politics, drawing on thinkers such as Burke, Cicero and Sartori. He recounts the pivotal milestones of the Partido Popular’s reinvention—including the 1989 renaming and the decisive 1990 Seville Congress—underlining the party’s strategic shift toward liberal–democratic values, institutional reform and national responsibility. With freedom and national loyality as its twin pillars, the Partido Popular emerged not merely as a reaction to socialism but as a principled, reformist force with a clear programme and a spirit of victory. Aznar’s chapter argues forcefully that effective governance must rest on authentic convictions, must be a principle-driven governance as a counter to populist and socialist tendencies.
