From Islam's inception to roughly the 1500s, the Islamic world and the Christian world appeared to be going down the same path. Yet for some reason nations such as England, France, Spain, and many others colonized much of the world while Oman and perhaps the Ottomans are the only two who somewhat embraced colonization(the Ottomans controlled a region of Indonesia called Aceh while Oman controlled parts of East Africa). Why did this change occur and what would happen if it didn't exist?
