26th century

In the 26th century, the (first) Earth Empire formed from an Earth-centred alliance of planets. It lasted until the late 30th century. Earth's single, planet-wide government was called EarthGov. (PROSE: Missing Adventures: Home)

Tensions existed between the Earth Empire and the Empire of the Draconians and even more so with the Daleks and the Korven. (TV: Frontier in Space, TV: The Korven)

Earth's Moon was used as a penal colony. (PROSE: Missing Adventures: Home)

Thanks to genetic engineering, humans no longer had wisdom teeth. (PROSE: Dry Pilgrimage)

Major events

 * 2520 - The Earth and Draconian Empires went to war after a misunderstanding led to an Earth ship destroying a Draconian ship.
 * 2540 - The Master, working for the Daleks, attempts to start a war between Earth and Draconia by attacking ships. The Third Doctor foils this plan.
 * Unknown (early century) - The Second Dalek War took place. Many planets were destroyed in the conflict. The war ended when the Tenth Doctor and the crew of the Wayfarer destroyed the Dalek ship Exterminator and its Dalek crew, leaving its leader, Dalek X, for dead. (PROSE: Prisoner of the Daleks)
 * The Cyber-Wars began in 2526.
 * Unknown (mid-century) - By mid-century (probably well before), much of what had been the southern United States had sunk under the "Mississippi Sea" — probably a much-expanded Caribbean Sea. (PROSE: Home)
 * Unknown (mid-century) - Space travel became relatively commonplace and affordable, though trips could be lengthy. It was common to sedate passengers for the longer trips. (PROSE: Biology Lesson on Mal Oreille)
 * Unknown (mid-century) - The Sontarans and the Rutans took their war to Chelsea 426. The Tenth Doctor stopped the Rutans and the Sontarans left before the colony collided with a Great White Spot. The Doctor prevented this as well. (PROSE: The Taking of Chelsea 426)
 * Unknown (late century) - Space travel appeared to be significantly faster by the end of the century; the approximately twenty-seven thousand light-year trip from Earth, near the edge of the galaxy, to Dellah, near its core, took about eleven months. (PROSE: Oh No It Isn't!)
