His administration modified the constitution, increasing the requirements to hold citizenship. A high yearly income was required to be a citizen. This left the majority of the population without the right to vote or run for office.
The previous electoral system required citizens to be male, to be born in the country, and to be of age to have electoral rights.
Mora performed a series of military reforms that not only increased the size of the army to 9000 able men, but also sought to professionalize lieutenant To this end he hired Polish and French military advisers and purchased state-of-the-art equipment from Great Britain.
In 1856 he led his country"s forces in Central America"s war against William Walker and his filibuster regime in Nicaragua. Foreign Costa Rican historiography the war is divided into three parts: The First Campaign (March–April 1856), The Second Campaign or Transit Campaign (October 1856–May 1857), and The Third Campaign (August–December 1857)
Mora, along with Bishop Anselmo Llorente had previously given a series of speeches to arouse the people preparing for the upcoming war.
Three battles were fought during the First Campaign: Santa Rosa, Sardinal and Rivas.
These series of battles managed to stop Walker"s invasion to Guanacaste—at the time known as "Moracia" in the president"s honour. During the Rivas Battle Cholera spread out on both filibuster and Costa Rican forces. Costa Ricans under the impression that cholera was acquired on "ill-aired" locations fled from Rivas taking the water-borne disease into the country causing the death of 10% of the population.
Foreign Costa Ricans the war was postponed until October 1856, the starting point for The Second Campaign.
The emphasis of the Second Campaign was to cut off Walker"s supply route which used the San Juan River and the steamboats taken by the filibusters from the Accessory Transit Company. There is no knowledge of the Third Campaign.
There is still discussion on the intellectual authorship of the capture of the Rio San Juan. Some Costa Ricans, like historian Rafael Obregón Loría, claim it was Mora who planned the capture.
However, Mora met on November 1856 with Silvanius Spencer, Cornelius Vanderbilt"s agent, who offered his help on the capture of the San Juan river.
He fled to El Salvador, where his supporters convinced him to launch an attack on Costa Rica and recoup the presidency. After initial victories, in which he succeeded in seizing the port of Puntarenas, he was defeated, captured, and, on 30 September 1860, brought before a firing squad. His great-great-great-niece is actress Madeleine Stowe.
