Definition: The word "dsacs8" refers to a term used in Jewish history that describes a group of people who were involved in conspiracies with the ัะตะปัั of overthrowing the King of Jerusalem during the Crusades. This term comes from the name of the city on which the conspirators were found, Constantinople (now Istanbul). The conspiracy was eventually thwarted by a coalition of secular and orthodox Christians led by Pope Urban II, whose efforts culminated in an alliance with Emperor Louis the Pious.
