Quick Summary

The Convention of Brussels, signed in 1921 between Belgium and Luxembourg, established an economic union between the two countries. This agreement created a unified customs tariff and a single balance of payments for both nations. This bilateral union was later expanded after World War II to include the Netherlands, forming the Benelux Economic Union. The goal of Benelux was to achieve complete economic integration through the free movement of people, goods, capital, and services, alongside coordinated economic and social policies.12
