Why did the Scots hate Charles?

The Scots harbored animosity towards Charles I due to his attempts to impose Anglicanism and centralize authority, which conflicted with their Presbyterian beliefs and desire for religious autonomy. His unpopular 1637 prayer book incited the National Covenant, leading to the Bishops' Wars. Additionally, his perceived disregard for Scottish interests and his authoritarian rule fueled resentment, culminating in the Covenanters' opposition and ultimately contributing to the English Civil War.
