Mellismo was a political practice of Spanish ultra- Right of the early 20th century. Born within Carlism, it was designed and championed by Juan Vázquez de Mella, who became its independent political leader after the 1919 breakup. The strategy consisted of an attempt to build a grand ultra-Right party, which in turn would ensure transition from liberal democracy of Restauración to corporative Traditionalist monarchy. Following secession from Carlism Mellismo assumed formal shape of Partido Católico-Tradicionalista, but it failed as an amalgamating force and decomposed shortly afterwards. Theoretical vision of de Mella is usually considered part of the Carlist concept and does not count as Mellismo; the strategy to achieve it does. In historiography its followers are usually referred to as Mellistas, though initially the term Mellados seemed to prevail. Occasionally they are also named Tradicionalistas, but the term is extremely ambiguous and might denote also other concepts.
