What were the first two industries impacted by the European union?

The first two industries significantly impacted by the European Union were agriculture and coal and steel. The establishment of the Common Agricultural Policy (CAP) aimed to stabilize agricultural markets, increase productivity, and ensure food security across member states. Meanwhile, the European Coal and Steel Community (ECSC) facilitated the integration and regulation of coal and steel production, fostering economic cooperation and reducing the potential for conflict in post-war Europe. These initiatives laid the groundwork for deeper economic integration within the EU.
