The history of tiaras is somewhat cloudy, but most jewelry historians credit the Egyptians for creating the first tiaras. Napoleon Bonaparte (1769-1821) had an influence on tiaras in more recent times; his love for announcing he and his family's affluence and nobility made the tiara a required accessory at all social functions during his reign. The tiara was at its heyday between the early 1800s and the beginning of World War I (1917-1920).
