Page "Council of Constance" Paragraph 4

Therefore, many voices, including Sigismund, King of Germany and Hungary ( and later Holy Roman Emperor ) pressed for another council to resolve the issue.

That council was called by John XXIII and was held from 16 November 1414 to 22 April 1418 in Constance, Germany.

According to Joseph McCabe, the council was attended by roughly 29 cardinals, 100 " learned doctors of law and divinity ," 134 abbots, and 183 bishops and archbishops.

An innovation at the Council was that instead of voting as individuals, the bishops voted in national blocks, explicitly confirming the national pressures that had fueled the schism since 1378.
