European Parliament: Structure, History, and Legislative Role

European Parliament

The European Parliament serves as the de facto lower house of the European Union's bicameral legislature. Founded on September 10, 1952, it has evolved from a consultative assembly into a powerful legislative body that represents the citizens of the EU. With its motto, In varietate concordia (United in diversity), the Parliament ensures that the diverse voices of member states are heard in the governing process of the Union.

History and Evolution

The institution was preceded by the Common Assembly of the European Coal and Steel Community. In its early years, it functioned primarily as a consultative assembly, providing advice rather than exercising direct legislative power.

A pivotal shift occurred between 1979 and 1985. The first direct elections were held from June 7–10, 1979, transforming the body into an elected Parliament. Over the following decades, its status grew significantly, exemplified by the overhaul of the Bolkestein directive, which signaled a major increase in the Parliament's legislative influence.

The Parliament's physical presence has also evolved. For years, plenary sessions were held in the Palace of Europe's hemicycle until a new building was constructed in Strasbourg in 1999.

Membership and Elections

MEPs are chosen by their respective member states using various voting systems. While most use Party list proportional representation (PR), Ireland and Malta utilize the Single Transferable Vote (STV). In Belgium's German-speaking electoral college, a de facto First-Past-The-Post (FPTP) or Single Member Plurality (SMP) system is used.
