League of the Macedonians

The League of the Macedonians (Greek: Κοινὸν τῶν Μακεδόνων, Koinòn tōn Makedónōn) was a confederationally-organized commonwealth institution (i.e., an ancient Greek regional state or koinon) consisting of all Macedonian communities united around a monarch. It can be paralleled from the koinon of the Molossians, but it seems that the Macedonian koinon had far less power than that of the Molossians. The capital, or headquarters, of the Macedonian koinon was the city of Beroia.
