The year 1831 was an important year in the history of Belgium. Belgium used to belong to the United Kingdom of the Netherlands. This action occurred at the Congress of Vienna in 1815. However, the people in the southern regions of the Netherlands weren’t pleased with King William I. The Catholics who lived in the South didn’t like the involvement of William I in their religious matters.
The revolution in Belgium began in 1830. William I sent troops to quell the uprising, but they weren’t successful in doing so. Belgium broke free from the Netherlands in 1830. A constitution was adopted in 1831. The first king of Belgium was Leopold I who ruled from 1831-1865. His son, Leopold II, took over in 1865 and ruled until 1909. Belgium grew economically during this time.
