Praexedes Mateo Sagasta

Sagasta, as leader of the Liberal Party, signed the Pact of El Pardo with Conservative leader Antonio Canovas del Castillo. This agreement formalized the turno pacifico, ensuring the peaceful alternation of power between the two parties after the death of King Alfonso XII.

Sagasta's government passed the Law of Associations, which legalized trade unions and political organizations. This law provided a legal framework for labor movements and political parties, fostering the growth of civil society in Spain.

As prime minister, Sagasta enacted the Law of Universal Suffrage for men over 25, replacing the previous census-based suffrage. This reform expanded the electorate significantly, though its impact was limited by continued electoral manipulation through caciquismo.

Sagasta was prime minister when the Spanish-American War broke out following the sinking of the USS Maine. Spain suffered a decisive defeat, losing its remaining colonies of Cuba, Puerto Rico, the Philippines, and Guam, marking the end of the Spanish Empire.
