Abstract:

Between 1993 and 2009, the EU consisted of three pillars. This structure was introduced with the Treaty of Maastricht in 1993, and was eventually abandoned in 2009, with the entry into force of the Treaty of Lisbon, which among others abolished the so-called second pillar of the EU “Common Foreign and Security Policy”. Today this role was taken over by several institutions and agencies, established for solving relevant questions, for examle the European Union Institute for Security Studies (EUISS), the European Union Satellite Centre (EUSC) and the European Defence Agency (EDA). The difference is that national acencies solve problems separately, whereas EU agency take into account commont foreign and security policy, under the supervision of the EU.
