France actually was in the same timezone as the UK before WWII and the German occupation. My grandma remembers switching to “German time”. Franco’s Spain similarly changed timezones in 1942 to match their German allies. So, yes, the change was made politically. :-) I’m guessing France is also responsible for Algeria and Morocco being in UTC+1, not sure if they’ve ever discussed changing zones.
Edit: I just checked and I was wrong about the Moroccan time zone. Algeria is in UTC+1 though (all year long, they don’t use DST), not sure why it’s in yellow on your map.
