This is a study in English of the Carlist Movement, the extreme right-wing party in Spain, during the climactic decade of the 1930s. Carlism represents the oldest existing movement of the traditionalist right in Europe. In 1931 Carlists had already been in conflict with Spanish liberalism and leftism for over a century, seeking to reverse the trends of the nineteenth century and restore a religiously inspired corporative monarchy and harmonious society. During the 1930s they attacked and plotted the overthrow of the democratic Second Republic, participated in the rising of 1936 and then played a major political and military role within Nationalist Spain. Dr Blinkhorn discusses Carlism's internal politics, power struggles and sources of support; its ideology; its relations with other elements in the Spanish right, principally Falangism and Catholic conservatism; its attitude towards the Republic, liberalism and the left; its view of contemporary events elsewhere in Europe; its stress on paramilitarism and conspiracy against the Republican regime; and its wartime role.
