[3] Before his death, Gregory XI substantially loosened the laws of the conclave: he instructed the cardinals to begin immediately after his death (rather than waiting the nine days prescribed by the Ordo Romanis) to prevent "factional coercion", he gave the cardinals permission to hold the conclave outside of Rome and move it as many times as necessary, and also seemingly suspended the two-thirds requirement, replacing it with "the greater part" (an ambiguous statement, in the original).
[1] The conclave was delayed one day because of a violent storm, and thereafter the seven Limoges cardinals wishing to leave Rome as Gregory XI had authorized them to were persuaded by the others that such an act would place the college in even more danger.
[3] The following September, the French cardinals reunited in Avignon, moved to Fondi, and elected Antipope Clement VII, who gained the support of all thirteen of his electors (at the time the entire College numbered twenty-two due to the death of Francesco Tebaldeschi).
[3] Inquisitor Nicholas Eymerich witnesses the conclave, and then went on to write one of the first tracts against Urban VI, Tractatus de potestate papali (1383), which argued in favor of the legitimacy of the Avignon line of papal claimants.
[8] The marked discrepancy between the classes of sources can be explained by the fact that the alleged duress of the mob became the primary argument in favor of the legitimacy of the Avignon claimants.
