Land empires were expansive states whose rulers exercised authority over large, substantially connected territories and diverse populations. They grew through conquest, diplomacy, alliances, migration, and the incorporation of subordinate peoples and states, while governing through systems ranging from centralized bureaucracies to provincial administration, tributary relationships, and local rulers. The twelve empires below are ranked by their greatest estimated contiguous territorial extent before 1880, excluding disconnected overseas possessions and territories beyond demonstrable imperial control.
- Mongol Empire (c. 1259) – c. 24.0 million km² – the largest contiguous land empire in history, combining highly mobile armies with regional governors, tribute systems, religious pluralism, and extensive Eurasian trade networks.
- Russian Empire (c. 1874) – c. 21.6 million km² – expanded across northern Eurasia through conquest, settlement, frontier forts, and Cossack expeditions, administering its vast territories through increasingly centralized imperial institutions.
- Qing Empire (c. 1790) – c. 13.1 million km² – reached its greatest extent under the Qianlong Emperor, combining Chinese bureaucratic government with Banner institutions, alliances, and distinct administrative systems across Inner Asia.
- Umayyad Caliphate (c. 730) – c. 9.9 million km² – expanded rapidly from the Iberian Peninsula to Central Asia through military conquest, governing through provincial administrations under the authority of the caliph.
- First Turkic Khaganate (c. 570) – c. 6.5 million km² – united much of the Eurasian steppe through mobile cavalry, dynastic alliances, tributary relationships, and control of important Silk Road routes.
- Achaemenid Empire (c. 500 BCE) – c. 5.5 million km² – governed a vast multicultural empire through satrapies, royal roads, tribute, standardized coinage, and accommodation of regional elites and traditions.
- Macedonian Empire (323 BCE) – c. 5.2 million km² – created through the conquests of Alexander the Great, combining Macedonian military power with inherited Achaemenid administrative networks and regional governors.
- Golden Horde (c. 1320) – c. 5.0 million km² – a major successor state of the Mongol Empire that exercised direct and tributary authority across the western Eurasian steppe and over the Rus' principalities.
- Roman Empire (117 CE) – c. 5.0 million km² – reached its maximum territorial extent under Trajan, supported by professional armies, provincial government, roads, taxation, urban networks, and extensive Mediterranean trade.
- Maurya Empire (c. 250 BCE) – c. 5.0 million km² – united much of the Indian subcontinent through military expansion and provincial administration, reaching its height under Ashoka.
- Ottoman Empire (c. 1683) – c. 4.8 million km² – governed territories across southeastern Europe, western Asia, and North Africa through provincial administration, military institutions, taxation, and negotiated relationships with local communities.
- Xiongnu Empire (c. 150 BCE) – c. 4.5 million km² – built a powerful Inner Asian confederation through mounted warfare, dynastic leadership, regional rulers, pastoral resources, trade, and tribute relations with Han China.
The scale of these empires depended on far more than conquest alone. Taxation, communications, trade networks, military logistics, political legitimacy, and cooperation with regional elites were essential to holding extensive territories together. Their histories also expose a recurring problem of imperial rule: the larger the territory, the greater the pressures created by distance, succession disputes, regional resistance, fiscal strain, and uneven control. Comparing their maximum extent therefore reveals not only how large land empires became, but also the different strategies—and limits—of governing space on a continental scale.
