These were empires primarily characterized by sea-based power and expansion, controlling trade routes and territories through naval dominance. Portugal, Spain, the Netherlands, France, and Great Britain provide historical examples. These empires differed substantially from land-based empires, focusing on establishing coastal trading posts and exerting influence over maritime trade networks rather than conquering large inland territories.
The rise of these empires transformed global trade and power dynamics. They facilitated the exchange of goods, ideas, and technologies across vast distances, leading to the Columbian Exchange and the intensification of global interconnectedness. Their control over vital trade routes brought immense wealth and influenced political structures, shaping modern nation-states and global economic systems.
