Some in Catalonia has been against the centralization of Spanish states since they were all folded into one state (1716) while Hong-Kong at it's earliest was created 1842 if I'm looking at the right details.

If we look at when an actual movement existed for Catalan Indepdendence, it was formed 1922 (Estat Català). Granted Hong-Kong wasn't really transfered until 1997, it seems unlikely Hong-Kongers have fought for independence for longer than Catalonia.

But in the end, there are no winners or losers here, only freedom fighters.
