From Belgium’s National Day that commemorates the formation of its monarchy, to Japan’s Marine Day, which honors the oceans and maritime heritage, and Singapore’s Racial Harmony Day, which promotes multicultural unity—21 July is rich with global importance.

🇧🇪 Belgium National Day – 21 July: A Nation’s Birth
📜 Historical Background
Belgium gained independence from the United Kingdom of the Netherlands following the Belgian Revolution in 1830. After a provisional government was formed, the country established a constitutional monarchy. On 21 July 1831, Prince Leopold of Saxe-Coburg-Gotha took an oath to become King Leopold I, officially becoming the first King of the Belgians.
That event is now seen as the symbolic foundation of modern Belgium, and 21 July is observed annually as Belgium’s National Day.
🏛️ Significance of the Date
The Belgian government chose 21 July in 1890 as the official national holiday because it highlights the establishment of the monarchy and constitutional governance—both central pillars of the Belgian state.
