Empires & Conquests
The great imperial powers that shaped borders, languages, and cultures across the world.
For most of recorded history, the largest political units on earth were empires — states in which a dominant power ruled over many peoples and territories. From the Achaemenid Persians and the Romans of antiquity to the Mongols who built the largest contiguous land empire ever known, empires spread languages, laws, religions, and technologies far beyond their origins.
Empires rose through a mixture of military conquest, administrative innovation, and economic power, and they fell through overextension, succession crises, invasion, and revolt. Their frontiers were never static: the same region might pass through Roman, Byzantine, Umayyad, and Ottoman hands over the centuries.
The imperial age reached its greatest global extent in the 19th and early 20th centuries, when a handful of European powers governed much of the planet — before two world wars and waves of independence movements dissolved the overseas empires in the decades after 1945.
