Since we have 1051 though 1099 available, I am choosing 1099: after the Kingdom of Jerusalem was established, the Al-Aqsa Mosque was made into the residential palace for the kings of Jerusalem. The Kings of Jerusalem, were the three main religions, Judaism, Christianity, and Islamic. At one time all three of the main religions of the world were in harmony and peace, and there was more peace on earth in that century and in that time than any other in history. Everyone got along like a bunch of Hippies!.



If anyone is a nerd like myself and wish to choose a number which is available and has significant historical meaning behind it, then please use the link below:
