But more frequently the Pope was the stronger. Then the Emperor or the King together with all his subjects was excommunicated. This meant that all churches were closed, that no one could be baptised, that no dying man could be given absolution — in short, that half of the functions of mediæval government came to an end.
More than that, the people were absolved from their oath of loyalty to their sovereign and were urged to rebel against their master. But if they followed this advice of the distant Pope and were caught, they were hanged by their near-by Liege Lord and that too was very unpleasant.
Indeed, the poor fellows were in a difficult position and none fared worse than those who lived during the latter half of the eleventh century, when the Emperor Henry IV of Germany and Pope Gregory VII fought a two-round battle which decided nothing and upset the peace of Europe for almost fifty years.
