This seal was made sometime during the reign of Emperor Henry of Flanders, so sometime between 1206 and 1216. Not too belong henry began his reign as emperor, the Crusaders leading the fourth Crusade (1202-1204) shifted their attention from attacking the Holy Land to conquering the Byzantine Empire, whose capital was in Constantinople. Constantinople is the city now known as Istanbul, in Turkey. Leading up to this conquest, the Byzantine empire was already suffering many problems, primarily the lack of control among their territories. The leaders of the Fourth Crusade, one of whom was Count Baldwin of Flanders, the future Latin Emperor and older brother of Henry, established the Pact of March 1204 in an attempt to create some unified political state. The Crusader attacks on Constantinople were passionate and fervent, and in April 1204, the Byzantine Greeks ruling in Constantinople were expelled by the Crusaders. The Crusaders founded the new Latin Empire, and named Baldwin of Flanders as their first emperor. Even though this was a massive feat, the empire would only last until its fall less than a century later in 1261.
