When did Macedonia become North Macedonia?
Macedonia is in Greece, North Macedonia is a piece of what used to be Yugoslavia.
One Macedonia is Hellenic (greek), the other is slavic.
The Greek part of Macedonia was the original kingdom of Macedonia in classical times but Philip of Macedon greatly enlarged the kingdom, so "North Macedonia" was part of what was known as Macedonia for upwards of 2000 years. Certainly longer than most members of the UN have been known by their present-day names.
