The Regionalist League was the dominant political party in Catalonia between 1901 and 1923. It represented moderate, socially conservative Catalanism that expressed the concerns of part of the industrial bourgeoisie, farm landowners and the middle class. Its political aims included self-government for Catalonia that would ensure that the country was modernised, and it sought to intervene in the affairs of the Spanish government in a pragmatic way that would lead to modernisation. The founding of the Mancomunitat de Catalunya in 1914 was its finest achievement as an institution.
