PLEASE HELP Explain ONE way that land-based empires policies to accommodate the ethnic diversity of their populations in the period 1450–1750.

No other era is as easy to summarize as the EARLY MODERN (1450-1750) era. This is the era the Europeans "wake-up", expand, and build empires. I'm not talking about Charlemagne here. I'm talking about the British Empire. I'm talking about the Dutch East India Trading Company. I'm talking about the Spanish Empire. This is a new Europe. This isn't Marco Polo. These Europeans will come to your land and stay there. They will take over most of the world in this era (if not, in the next). Beyond the Maritime empires (and the effect of their establishment), many huge land empires emerged (most notably the Islamic Mughal and Ottoman Empires). Of course, China is important. It always is. So, here is the Early Modern Period.
