Мартин IV
On 22 February 1281 a new Pope was selected, Pope Martin IV, a Frenchman Geanaklopos describes as "blindly subservient" to Charles of Anjou. Once again, Charles had no clear brake on his ambitions to conquer Constantinople, and he moved swiftly to prepare for this new offensive. One early move was taken by Pope Martin, who on 18 October 1281 excommunicated Michael without any warning or provocation, thus disrupting the union of Lyons.
