Dependent on Charles of Anjou in nearly everything, the new Pope quickly appointed him to the position of Senator of Rome. At the insistence of Charles, Martin IV excommunicated the Eastern Roman Emperor Michael VIII Palaeologus, who stood in the way of Charles's plans to restore the Latin Empire of the East that had been established in the aftermath of the Fourth Crusade. He thus broke the tenuous union which had been reached between the Greek and the Latin Churches at the Second Council of Lyons in 1274 and further compromise was rendered impossible.
