In the 7th Century, the Arabs expanded out of the Arabian peninsula, conquering huge amount of lands, spreading their religion and culture, ignited a Golden Age and transformed the World as we know it. In this thread, the topic is about the Arabs expanding into Afghanistan, Central, East and parts of South Asia as they did into the Levant and Egypt, Arabizing these regions and making them core Arab regions in a few centuries and settling one or more beautiful capitals with advanced libraries, courthouses, building new planned cities like Baghdad, grand mosques, Sufi centers, etc. How would all this work out? How would this effect the future of the region when they replace the Mughals and the Turks as a Muslim empires? How would they survive and effect the Mongol invasions? How would India, further South, take shape? How would Islam look like?
