The Constitution of 1869 kept the traditional denomination of Prince of Asturias due to the influence of the Asturian politician José Posada Herrera. Alfonso XII ascended the throne in 1874 following the end of the brief First Spanish Republic and as the infanta Isabella was the immediate heir to the Crown after her brother Alfonso, she once again became "Princess of Asturias" by royal order of 25March 1875, applying the doctrine of 1850 by granting the title of Princess without distinguishing between male or female successor. The subsequent Constitution of 1876 omitted the title again from its provisions, similar to the constitutions of 1837 and 1845.
