The Mancomunitat of Catalonia was dissolved during the dictatorship of Miguel Primo de Rivera in 1925. The anti-Catalan measures taken by dictator Primo de Rivera led to further disappointment among Catalan conservatives, who initially trusted in him because of an earlier support of regionalism prior to his "pronunciamiento" in September 1923, and also further exacerbation of insurrectionary nationalists. In November 1926 Macià helmed an attempt of military invasion of Catalonia from France which would purposely lead to a civil uprising and the proclamation of the Catalan Republic; he was not able even to get past through the border.
