3.1 Empires Expand

Between 1450 and 1750, powerful states arose across Eurasia that depended on the combination of gunpowder weapons, disciplined armies, and centralized administrations to expand and rule their territories. These empires created new forms of political authority and altered the balance of power between regions. The Ottomans, Safavids, Mughals, and Qing each developed distinct strategies for maintaining control, but all relied on the ability to command loyalty, collect taxes, and project military strength. The diffusion of gunpowder technology from East Asia to the Islamic world and then into Europe allowed rulers to dominate rivals and build empires on a scale not seen since antiquity.
