Avignonese "antipope" Benedict XIII has resisted the pressure on him to abdicate, arguing that abdication is uncanonical.

Pointing out that he is the only surviving cardinal from before the Great Schism, Benedict concludes that his vote is the only one that is certainly valid, and he would, of course, choose himself.

The obstructive tactics of Benedict and the Roman claimant, Gregory XII, cause the cardinals of Rome and Avignon to despair of getting any cooperation from them toward unity.

Abandoning both, the cardinals summon the Council of Pisa in 1409, a general assembly of the Roman Catholic Church, recognized by neither claimant.
