In the Islamic world, after the fall of the Timurid Renaissance, powers such as the Ottoman, Suri, Safavid, and Mughal empires grew in strength (three of which are known as gunpowder empires for the military technology that enabled them). Particularly in the Indian subcontinent, Mughal architecture, culture, and art reached their zenith, while the empire itself is believed to have had the world's largest economy, bigger than the entirety of Western Europe and worth 25% of global GDP, signalling the period of proto-industrialization.
