Over the next few years, there were several Scottish rebellions against Edward (for example, in 1297 under William Wallace and Andrew Moray). The rebels would invoke the name of "King John", on the grounds that his abdication had been under duress and therefore invalid. This claim came to look increasingly tenuous, as John's position under nominal house-arrest meant that he could not return to Scotland nor campaign for his release, despite the Scots' diplomatic attempts in Paris and Rome. After 1302, he made no further attempts to extend his personal support to the Scots. Effectively, Scotland was left without a monarch until the accession of Robert the Bruce in 1306.
