Which nationalist leader led laos to independence?

Prince Souphanouvong led Laos to independence from French colonial rule in 1949.

Are you sure?

I apologize for the error in my previous response. Prince Souphanouvong was a prominent figure in the nationalist movement in Laos, but it was actually Prince Souvanna Phouma who played a crucial role in leading Laos to independence from France in 1953. Souvanna Phouma would go on to become the first Prime Minister of independent Laos. Thank you for pointing out the mistake.
