Duchy of Saxe-Meiningen
Her husband had sold the District of Schalkau to the Duchy of Saxe-Meiningen in 1723, in order to raise money. She regarded this sale as illegal. Influenced by Prince Joseph of Saxe-Hildburghausen, who was in Hildeburghausen at the time, Sophia Albertine declared war on Saxe-Meiningen and had Schalkau occupied militarily on 11 July 1724.
