During the period from 570-1000 CE, the Arab empire experienced a golden age of trade and urbanization. Major cities like Baghdad, Cairo, and Damascus served as centers for trade along the Silk Road as well as administrative and cultural hubs. Ships and caravans traded goods like gold, slaves, silk, spices, and other commodities across Africa, Asia, and Europe. This flourishing trade led to large, prosperous cities and the rise of Islamic architecture including grand mosques and palaces.
