Which three regions share power in federal Belgium?

Following the constitutional reforms of the 1970s, 1980s, and 1990s, Belgium transitioned from a unitary state to a federal state. National authorities now share power with executive and legislative bodies representing three self-governing regions:12

• Flanders (the Flemish Region)
• Wallonia (the Walloon Region)
• Brussels-Capital Region

These regional authorities hold primary responsibility for matters such as the environment, energy, agriculture, transportation, and public works. They also share responsibility with the national government for economic affairs, labor, and foreign trade. In addition to these regions, power is also shared with the country's three major language communities: the Flemish, French, and German communities, which hold authority over cultural matters, education, and the use of language.2
