Manuel García Prieto, 1st Marquis of Alhucemas (5 November 1859 – 8 March 1938) was a Spanish politician who served as prime minister several times in his life and as the 30th Solicitor General of Spain.

[1][2] Formed in the law firm of Eugenio Montero Ríos, García Prieto entered the former's cacique network and married one of his daughters, María Victoria.

[3] Following the assassination of Prime Minister José Canalejas in 1912, and the ensuing factional division within the Liberal Party, García-Prieto led the so-called demócrata ("democratic") minority, rival of the romanonista majority.

[4] On 27 November 1912, he and French ambassador to Spain Léon Geoffray signed the Treaty between France and Spain regarding Morocco, which established de jure Spanish zones of influence in northern and southern Morocco, both zones already under de facto Spanish control, while France remained the primary colonial power as the sole non-Moroccan state signatory of the 1912 Treaty of Fes.

[5][6] Within the cadres of the Liberal party, the Marquis of Alhucemas espoused just like Miguel Villanueva the policy of neutrality of Spain during World War I, forcing pro-ally Romanones to resign as Prime Minister in 1917.
