Happy birthday to Leopold of Saxe-Coburg-Saalfeld, Charlotte’s beloved husband! He was born on 16 December 1790 in Ehrenburg Palace in Coburg as the youngest son of Francis, Duke of Saxe-Coburg-Saalfeld, and Countess Augusta Reuss-Ebersdorf. You can read about his life before the marriage with Charlotte here
When it comes to his later life as the King of Belgium, I strongly recommend you visit his Facebook page where you can find a lot of details about his reign gathered by the admins of the page. Their work deserves acknowledgement (and a like if you haven’t liked the page yet).
