Question: What is the date of death of Marie Joséphine Of Savoy's husband?
Sentence (from "Louis XVIII of France"): Louis had no children, so upon his death the crown passed to his brother, Charles X. Louis XVIII was the last French monarch to die while still reigning, as Charles X (1824–1830) abdicated and both Louis Philippe I (1830–1848) and Napoleon III (1852–1870) were deposed.
Relevant evidence: No
