I’m torn between “Every people deserves the right to self-determination” and “Catalunya is richer than Spain, so it’s the bourgeosie wanting to split off from the poors and pay less tax”

independence movements in colonized countries, even the ones that went left afterward involved to some extent rightist nationalists. the only event conforming to your general rule is the dissolution of the USSR, which distinctly marginalized the left since the left are the ones who were overthrown. other countries it’s not so discrete, look at Africa or South America, leftwing and conservative independence movements have both been successful, and have often overthrown each other after independence.
Independence movements in post-WW1 Europe also mostly produced right-wing nationalistic countries with short-lived Hungarian Soviet Republic as the only exception (that got crushed by other newly formed countries).
Former colonies is murkier question, but even there things often didn’t improve for the left (although interference from imperial powers often played a decisive role in shifting the political dominance to rightists there).
