Critics of Islam need to know about the Islamic “Golden Age” because it will be thrown at them on various occasions. That Golden Age ended in the 13th century A.D… Actually, according to many historians, it ended even earlier than that — in the 12th or even the 11th century.
True, at this period there was a lot of culture and civilization in the Muslim world (depending on when and depending on where). Yet that was around eight centuries ago — at the least! Not only that: virtually the entire Islamic Golden Age was engendered by the influence of Greek philosophy and science; as well as of Jewish and Christian theology, and Persian and Indian culture.
It is, therefore, a sign of desperation that Muslims need to go back so far in order to sell us the idea that Islam “is a religion of culture… and peace”.
