Luis Hernando de Larramendi Ruiz was a Spanish Carlist politician and theorist. Though his term as a party jefe was rather short (1919-1921), he stands out as monumental figure in history of the 20th-century Carlism, remaining among its leaders for some 40 years and taking part in decision-making process from the mid-1910s until the mid-1950s. As author he is recognized for his 1937 work, El sistema tradicional, an orthodox lecture of Traditionalism.

Electoral Carlism of Restoration was vital to sustain Traditionalism in the period between the Third Carlist War and the Primo de Rivera dictatorship. Carlism, defeated in 1876, during the Restauración period recalibrated its focus from military action to political means and media campaigns. Accommodating themselves to political framework of the Alfonsine monarchy, the movement leaders considered elections, and especially elections to Congreso de los Diputados, primary vehicle of political mobilization. Though Carlist minority in the Cortes remained marginal and its impact on national politics was negligible, electoral campaigns were key to sustain the party until it regained momentum during the Second Spanish Republic.
