Why did nationalist tensions emerge in the Balkans ?
The Balkans was a region of geographical and ethnic variation comprising modern-day Romania, Bulgaria, Albania, Greece, Macedonia, Croatia, Bosnia-Herzegovina, Slovenia, Serbia and Montenegro whose inhabitants were broadly known as the Slavs. As the different Slavic nationalities struggled to define their identity and independence, the Balkan area became an area of intense conflict. The Balkan states were fiercely jealous of each other and each hoped to gain more territory at the expense of the others. Matters were further complicated because the Balkans also became the scene of big power rivalry.
