Greece and Macedonia have spent decades bitterly arguing over the latter's name, but recent developments have put the two on better terms than they've been in years. Officials from both countries have met several times since mid-2017; most recently, Greek Prime Minister Alexis Tsipras met his Macedonian counterpart, Zoran Zaev, during the World Economic Forum in Davos, where they exchanged gestures of goodwill and promised to continue negotiations to resolve their differences. Then from Jan. 30-31, a U.N. mediator visited Athens and Skopje to build bridges between the governments. These are not minor developments for two countries that have spent decades accusing each other of trying to steal the other's identity and territory. The conflict between Greece and Macedonia has its roots in historical, cultural, geographic and political factors.
