No place has seen the paradox of supranationalism and devolution more than europe. discuss the european paradox" with respect to the rise of supranationalism occurring simultaneously with devolution/balkanization during the last 50 years."

Ideas for a supranational state arose after the World War II, with the goal of preventing another catastrophe. Supranationalism refers to a large amount of power given to an authority which is in theory placed higher than the state (for example, European Union). Economic partnership helped form this Union of states. At the same time, some people feared that their states would lose their sovereignty, even farther there was a rising tendency towards formation of new independent countries (Catalonia, Baskia, Valonia, South Tirol, etc.). These national movements were economically powerful and saw themself in a position to form a new national identity which will then cooperate with other states elements - countries in this supranational state (the European Union).
