Abadal i de Vinyals was born in
Vic. He graduated in law at the
University of Barcelona in 1910. He also completed studies in history in both Barcelona and in several French centers. Towards 1909-10 he was affiliated with Joventut Nacionalista, the youth wing of la Lliga Regionalista (the
Regionalist League). Shortly thereafter his political career began, which included terms as the provincial member of parliament for Vic (1917 and 1921). In the
Commonwealth of Catalonia, he worked at numerous commissions – including that of the
Biblioteca de Catalunya (Library of Catalonia) - and he was a vice-president of the Board of Education. He was a promoter of Accio Catalana, which he left when the Republic was founded, returning to la Lliga. He was the director of the newspaper
La Publicitat when it was ‘catalanized’ (1922), and also the effective director of
La Veu de Catalunya (1933–36). He was also one of the founders of the newspaper ''L'Instant'' (The Instant) (1935). In 1936, he moved to Italy, and in 1939 he returned to Catalonia, dedicating himself to the study of history, with special attention to the period of the Catalan counts and its antecedents. He died in 1970 in
Barcelona. ==Work==
