Islamic civilization and its achievements are a significant link and era during middle ages that had been intentionally or un-intentionally erased from common man's history. Now many western historians are reopening that chapter and are acknowledging the great contributions Islam and Muslims made in every field of life. Building on achievements of previous civilizations, research done during Muslim era (700 - 1500 CE) lead to the improvement and understanding in various fields of science, art and culture and not only benefited mankind but also formed the basis of modern research and European Renaissance. This account of various developments is aimed to provide the missing link between the middle ages and modern times. It provides a dynamic picture to not only Muslim generations but to generations of every faith and nation. It also highlights the fact that when achievements and potentials of different nations and cultures are put together and worked on, the knowledge becomes fruitful and generations make progress with it.
