Empire

You may be looking for the cinema.

An empire was a state which controlled more than one culturally distinct population groups. These were often different planets and/or species. Empires were usually led by an emperor, (TV: Nightmare in Silver) or empress, (TV: Empress of Mars) who could be elected or hereditary.

The First Doctor told his companions Vicki Pallister and Steven Taylor that every empire in the history of the galaxy eventually collapsed. (AUDIO: Upstairs) Ashad agreed with this, but noted that empires could rise again. (TV: Ascension of the Cybermen)

Human empires

There were many empires through time and space. Earth itself had several empires in its history. One of its earliest known empires was the Roman Empire, that centred in the city of Rome. (TV: The Big Bang) Although it eventually fell, (TV: Day of the Moon) it would later come about again as the New Roman Empire, a civilisation that flourished around the year 12005. (TV: The End of the World)

The Huns ruled a vast tribal empire centred around the region that would later become Kazakhstan. (PROSE: Combat Magicks)

The largest Earth empire encompassed by a single nation was the British Empire, the empire of the United Kingdom which spread across the Earth. (TV: Tooth and Claw, The Empty Child, Empress of Mars, Demons of the Punjab) By 1850, it was considered the most powerful empire in Earth's history up to that point. (AUDIO: 1963: The Assassination Games) The nation of Japan also had it's own empire, which was the prominent power in Asia during the first half of the 20th century.

(PROSE: The Face of the Enemy) The Japanese and British Empires fought against each other during the Second World War.

(PROSE: Magic of the Angels)

Humanity also grew to eventually have galactic empires. While the date is uncertain, the first official Earth Empire formed in either 2501 by EarthGov, (PROSE: The Monsters Inside) or 2530s, by the Earth Federation. (PROSE: The Colony of Lies) By around the year 4000 (TV: The Daleks' Master Plan) the Earth Empire's successor, the First Great and Bountiful Human Empire came into being.

(TV: Planet of the Ood) Humanity later developed the Third Great and Bountiful Human Empire, which the Eleventh Doctor described as "neither great, nor bountiful, nor overwhelmingly human".
