Why is Brussels the capital of Belgium?

Brussels was named the capital of Belgium following the country's independence in 1830. Its designation as the capital and seat of government was established in the constitution adopted by the newly elected National Congress, largely due to the city's pivotal role in the uprising against the Kingdom of the Netherlands.1

Historically, Brussels had long served as a center of political and administrative power. During the 15th century, it became the seat of central administrative bodies for the Burgundy ducal possessions in the Low Countries. This status was solidified in the 16th century under Charles V, who permanently established his government councils in the city. Even during the period of the United Kingdom of the Netherlands (1815–1830), Brussels shared the status of capital with The Hague, maintaining its prominence before becoming the sole capital of the independent Belgian state.1
