The Pope as International Peace Mediator in the 19th CART-2021-126420During the second half of the 19th century, a utopian project was composed around an idea of the world under the influence and the moral authority of the Pope. After the Pope''s loss of power, Catholics imagined new ways to restore his authority both within ad outside the Catholic Church. Central to this ultramontane utopia was the project of turning the pope into an international peace mediator. In order to legitimise that utopian programme, they looked back to an idealised medieval past, and tried to find references to prove his moral authority outside the confessional frameworks of Catholicism. In order to study these utopian projects, this paper focuses on the speeches and requests for international arbitration made by Catholics at the congresses held in Spain between 1889 and 1899.2021http://zaguan.unizar.es/record/15131910.14198/PASADO2021.23.05http://zaguan.unizar.es/record/151319oai:zaguan.unizar.es:151319info:eu-repo/grantAgreement/ES/AEI/PID2019-105071GB-I00info:eu-repo/grantAgreement/ES/AEI/PID2019-108299GB-C21info:eu-repo/grantAgreement/ES/RYC2019-026405-I/AEI/10.13039/501100011033Pasado y memoria 23 (2021), 117-138byhttps://creativecommons.org/licenses/by/4.0/deed.esinfo:eu-repo/semantics/openAccess
