The best response to how the development of maritime empires compares with land-based empires in the fifteenth and sixteenth centuries is:
The maritime empires focused on control of trade routes in the Indian Ocean rather than the control of people and land.
This reflects the primary goal of maritime empires, which was to establish trade networks and control key shipping routes, leading to economic gain rather than direct territorial conquest and governance, as was more typical with land-based empires.
