Ramadan Kareem! Listen to this incredibly detailed overview of the very first Islamic empire, dynasty, and kingdom - the Rashidun Caliphate. Beginning immediately after the passing of the prophet Mohammed (PBUH), this empire only lasted 29 years. During this short time period, the Islamic holy book, the Qur'an, was codified and preserved, the Islamic calendar was created, and Islam spread to a large swathe of land in the modern South West Asia region. Thank you to Zainab Nouri Al Mufti for writing such a spectacular Civilization 101!
