Jerusalem has been crowned queen of the world's cities for 50 centuries. Chosen by God to be the bulwark of monotheism, Jerusalem was first mentioned in the Bible during the time of Abraham under the name of Salem, meaning peace. The King of Salem was a Jebusite and in the 10th century BC, David captured the city from the Jebusites and made it his capital. First inhabited by the Canaanites, Jerusalem has been besieged more than 50 times, conquered 36 times, and destroyed 10 times. In 330 AD, Constantine converted Jerusalem into a Christian city and sent his mother, Helena, to build its first churches.
