Egyptomania refers to a period of renewed interest in the culture of ancient Egypt sparked by Napoleon's Egyptian Campaign in the 19th century. Napoleon was accompanied by many scientists and scholars during this Campaign, which led to a large interest after the documentation of ancient monuments in Egypt. The ancient remains had never been so thoroughly documented before and so the interest in ancient Egypt increased significantly. Jean-François Champollion deciphered the ancient hieroglyphs in 1822 by using the Rosetta Stone that was recovered by French troops in 1799 which began the study of scientific Egyptology.
