The 1431 papal conclave (March 2–3) convened after the death of Pope Martin V and elected as his successor Cardinal Gabriele Condulmer, who took the name Eugene IV.

Pope Martin V initiated the custom of creating cardinals without publishing their names at the time (similar to in pectore).

[citation needed] At the time of his death the names of two of his secret nominees remained unpublished and, therefore, they were not regarded as members of the Sacred College.

They were Juan Casanova, administrator of Elne, and Guillaume Ragenel de Montfort, bishop of Saint-Malo, and they both were later created again by Eugene IV.

[2] The terms of the Capitulation, which contained at least eight clauses,[3] included: The first scrutiny took place on the following day, 3 March, and ended with unanimous election of Cardinal Gabriele Condulmer, who took the name of Eugene IV.
