In 1963, the president of the Provincial Council, Pedro Escalante y Huidobro, proposed reapplying the name of Cantabria to the Province of Santander, as suggested in an academic report written by the historian Tomás Maza Solano. Although further steps were taken and many of the townships were in favour of the move, the petition did not succeed, mostly due to the opposition of Santander City Council. On 30 December 1981, a process that had been started in April 1979 by the Council of Cabezón de la Sal, under the presidency of Ambrosio Calzada Hernández, culminated in the granting of self-rule to Cantabria, outlined in Article 143 of the Spanish Constitution.
