At the same time, the Greek–Romanian antagonism over Aromanian loyalties intensified with the armed Macedonian Struggle, leading to the rupture of diplomatic relations between the two countries in 1906. During the Macedonian Struggle, most Aromanians participated on the "patriarchist" (pro-Greek) side, but some sided with the "exarchists" (pro-Bulgarians). However, following the Balkan Wars of 1912–13, Romanian interest waned, and when it revived in the 1920s it was designed more towards encouraging the Romanians' "Macedonian brothers" to emigrate to Southern Dobruja, where there were strong non-Romanian minorities.
