EU Treaties are formal agreements that establish the legal framework for the European Union (EU). They outline the principles, objectives, and functioning of the EU, including the rights and responsibilities of its member states. Key treaties include the Treaty of Rome, the Maastricht Treaty, and the Lisbon Treaty, each contributing to the evolution of the EU. These treaties are essential for the governance of the EU, as they define its institutions, decision-making processes, and policies. They also address important issues such as trade, security, and human rights, ensuring cooperation among member states and promoting integration within the European Community.
