List of largest empires explained

Several empires in human history have been contenders for the largest of all time, depending on definition and mode of measurement. Possible ways of measuring size include area, population, economy, and power. Of these, area is the most commonly used because it has a fairly precise definition and can be feasibly measured with some degree of accuracy.[1] Estonian political scientist Rein Taagepera, who published a series of academic articles about the territorial extents of historical empires between 1978 and 1997,[2] [3] [4] [5] defined an empire as "any relatively large sovereign political entity whose components are not sovereign" and its size as the area over which the empire has some undisputed military and taxation prerogatives.[6] The list is not exhaustive owing to a lack of available data for several empires; for this reason and because of the inherent uncertainty in the estimates, no rankings are given.

Largest empires by land area

For context, the land area of the Earth, excluding the continent of Antarctica, is NaNabbr=onNaNabbr=on.

Empires at their greatest extent

Empire size in this list is defined as the dry land area it controlled at the time, which may differ considerably from the area it claimed. For example: in the year 1800, European powers collectively claimed approximately % of the Earth's land surface that they did not effectively control.[7] Where estimates vary, entries are sorted by the lowest estimate. Where more than one entry has the same area, they are listed alphabetically.

Timeline of largest empires to date

The earliest empire which can with certainty be stated to have been larger than all previous empires was that of Upper and Lower Egypt, which covered ten times the area of the previous largest civilisation around the year 3000 BC.[36]

Largest empires by share of world population

Because of the trend of increasing world population over time, absolute population figures are for some purposes less relevant for comparison between different empires than their respective shares of the world population at the time.[38] For the majority of the time since roughly 400 BC, the two most populous empires' combined share of the world population has been 30–40%. Most of the time, the most populous empire has been located in China.[39]

[I]n 1800 Europe and its possessions, including former colonies, claimed title to about 55 percent of the earth's land surface: Europe, North and South America, most of India, and small sections along the coast of Africa. But much of this was merely claimed; effective control existed over a little less than 35 percent, most of which consisted of Europe itself. By 1878—that is, before the next major wave of European acquisitions began—an additional 6,500,000 square miles (16,800,000 square kilometers) were claimed; during this period, control was consolidated over the new claims and over all the territory claimed in 1800. Hence, from 1800 until 1878, actual European rule (including former colonies in North and South America), increased from 35 to 67 percent of the earth's land surface..
