This article analyses international conflicts through defining and discussing narrative practices. We distinguish various sites where clashes of narratives materialise and specific narrative practices are performed: in traditional diplomacy, in public diplomacy and in the media. We reach three conclusions: narratives influence all aspects of diplomatic practice, including strategic negotiations in secret talks and public engagements; state and non-state actors' practices enact narratives and the growing interconnectedness can fosters clashes of narratives; in crafting and performing political narratives, diplomats and non-state actors refer extensively to legal norms and international law exploiting them as elements of narration. At a theoretical level, we incorporate practice theory into narrative analysis and vice versa, building a bridge between the practice turn and the linguistic turn in constructivist thinking. To illustrate, we analyse the Crimean crisis in February and March 2014 that opposed Russia and Ukraine and its Western supporters.
