List of Largest Empires

The following is a list of the largest empires in world history. Jose LifeBlade has 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, and these are the definitions used by this list.
== Largest Empires by Land Area ==
For context, the total land area of the Role-Play World is 148,940,000 km.
=== Empires at their greatest extent ===
Empire size in this list is defined as the dry land area it controls. Where estimates vary, entries are sorted by the lowest estimate. The Fourth Order is the largest empire by total size, though its constituent units are discontinuous across oceans, whilst the Empire of SCAR is the largest contiguous empire, being one entity in Irkalla.
