The Treaty of Lisbon, signed in 2007, aimed to enhance the efficiency and democratic legitimacy of the European Union (EU). By amending the existing treaties, it sought to streamline decision-making processes and establish a more coherent foreign policy framework. Key innovations included creating a permanent President of the European Council and a High Representative for Foreign Affairs and Security Policy. The treaty reinforced the role of the European Parliament in legislative processes and expanded the scope for community action. Ultimately, the Treaty of Lisbon intended to strengthen the EU’s position on the global stage and improve its ability to respond to contemporary challenges.
