Why did some Edmund Burke support the American revolution but not the french revolution?

Edmund Burke supported the American Revolution because he viewed it as a legitimate struggle for rights and self-governance against British tyranny, aligning with his belief in gradual reform and respect for tradition. In contrast, he opposed the French Revolution, perceiving it as a radical upheaval that rejected established institutions and traditions, leading to chaos and violence. Burke believed the French Revolution's ideology threatened social order and stability, which he valued highly. Thus, his support was rooted in his defense of gradual change over revolutionary extremism.
