Då Ryssland tog tillbaka Krim från Ukraina.
En fallstudie av den ryska erövringen av Krimhalvön 2014.
Abstract This thesis is a case study aiming to give explanations to Russia?s annexation of Crimea in March 2014. By using three different theoretical perspectives, realism, regional hegemony and constructivism, the aim is to find different but also complementing explanations to the case. The theories realism and regional hegemony are related and also similar to each other, but still contributes with some different focuses on the case. Both realism and regional hegemony has their main focus on the sovereign state?s security and their power militarily, politically and economically. Constructivism on the other hand is a bit different from the other two, and has its main focus on identity, ideas and worldviews. Thanks to the differences between the three perspectives the analysis gives a broader and deeper explanation to Russia?s invasion and annexation of Crimea.
