Bishop of RomePortrait of Martin V by Pisanello
Crusades[edit]
According to Burton, Pope Martin authorized a crusade against Africa in 1418 in relation to the slave trade.[7]
In addition to the Hussite Crusades, Martin declared a Crusade against the Ottoman Empire in 1420 in response to the rising pressure from the Ottoman Turks. In 1419–1420 Martin had diplomatic contacts with the Byzantine emperor Manuel II, who was invoking a council in Constantinople. On 12 July 1420 the Pope conceded to attach an indulgence to anyone who would contribute to a crusade against the latter, which would be led by Sigismund, King of the Romans.[4]
