In the Balkan Wars of 1912-1913, the Greek army crossed into Macedonia and took possession of 51% of the whole country including its largest city of Salonica.

The decree of Georgios I, the King of the Greeks, issued on October 31, 1912, acknowledges by the king himself that the “territories in Macedonia (are) occupied by the Greek army”:

Georgios I – The King of the Greeks

Taking into account the developed need for the urgent and temporary organization of the administration of the territories in Macedonia, occupied by the Greek army. At the proposal of the Ministerial Council, we have decided and command the following. The Minister of Justice Mr. K. Raktivan, as representative of the Greek Government, is instructed to organize the affairs concerning the temporary administration of the occupied territories. The president of the Ministerial Council is to announce and carry out this decree.

It is clear that Macedonia was not “liberated” by the Greek army (as the modern Greeks claim) today but occupied by the same. One liberates ones own territory from foreign rule, and only foreign territories are occupied.
