Christianity, strangely enough. Since Christianity had become a state religion in the Roman Empire, having the Roman Emperor to thank for that, it had developed the principle that an emperor or king was not just some uppity general, but 'God's anointed', certainly if the anointing had been done by the Pope or one of his bishops.
The year 1000 AD was the period that Christianity became the state religion in northern and eastern Europe. Until then, succession in these parts had always been the survival of the strongest contender and 'heathen' kings were little more than the first among equals, who had to prove themselves constantly to keep their position. After the advent of Christianity, the kings that were willing to convert were rewarded by the bishops and priests telling their subjects that he held the throne 'by the grace of God' and rebelling against him was to rebel against God and the natural order of things as the Church saw it.
Also in Western Europe, with the growing power of the Church organization came the ever-stronger support of the king's position by the Church. On the other hand, in the rare cases where a king fell out with the Pope the church saw no problem in excommunicating him and telling his subjects that they should no longer regard him as their lawful ruler.
