Empire vs. Kingdom: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Updated on October 11, 2023
An empire typically governs diverse territories and peoples usually obtained through conquest, whereas a kingdom is a single sovereign nation often unified by language and culture.

Key Differences

An empire embodies extensive groups of territories and peoples, all under a single supreme authority, often an emperor. This dominant authority characterizes an empire with the diverse regions and different cultures that it subjugates and governs. Unlike kingdoms, empires often expand their territories through conquest, absorbing various cultures, languages, and regions into a single political entity. For example, the Roman Empire enveloped various territories across Europe, Africa, and Asia, all under a centralized Roman governance.
On the other hand, a kingdom represents a political and geographical entity ruled by a king or queen, typically bound by a common language and culture. Unlike an empire, a kingdom might not embody a large, expansive territory or a collage of diverse cultures and languages. Kingdoms are often singular entities, sometimes established within the confines of natural geographic barriers or boundaries, and primarily homogenous in cultural and linguistic aspects. The Kingdom of Norway, for example, stands as a sovereign nation without substantial dominance over various other territories and cultures.
Empires often find their narratives interwoven with stories of conquest, expansive territorial dominance, and intricate governance over assorted cultures and languages. Historical empires, such as the British Empire, showcase a colossal impact over numerous continents, influencing various cultures, languages, and territories globally. Empires often exhibit a complex administrative machinery to govern the various, sometimes incongruent, entities within it, ensuring stability and control across large territories.
In contrast, kingdoms typically showcase a more unified narrative, with governance, culture, and territorial bounds that are often simpler and more homogenous than empires. A kingdom usually stands sovereign and might establish alliances or treaties with other nations but does not govern them directly. Kingdoms, such as the Kingdom of Denmark, have a noticeable unity in culture and administration, primarily governing territories that associate themselves directly with the cultural and administrative center.
One might find that while both empires and kingdoms symbolize forms of governance and territorial control, they distinctively vary in their scope, diversity, governance, and cultural composition. An empire, with its vast territories, diverse cultures, and complex administrative requirements, often stands in contrast to a kingdom, with its typically more uniform, culturally cohesive, and administratively straightforward structure.
