26th century

In the 26th century, the (first) Earth Empire forms, out of an Earth-centered alliance of planets. It will last until the late 30th century. Earth's single, planet-wide government is called Earthgov. (BFBS: Missing Adventures: Home)

Tensions exist between the Earth Empire and the Empire of the Draconians and even more so with the Daleks and the Korven. (DW: Frontier in Space, K9TV: The Korven)

Earth's Moon is being used as a penal colony. (BFBS: Missing Adventures: Home)

Thanks to genetic engineering, Humans no longer have wisdom teeth. (BNA: Dry Pilgrimage)

Major Events

 * Unknown (Early Century) - The Second Dalek War takes place. Numerous planets were destroyed in the conflict. The war was stopped when the Doctor and the crew of the Wayfarer destroyed the Dalek ship Exterminator along with its Dalek crew, and leaving its leader, Dalek X, for dead. (NSA: Prisoner of the Daleks)
 * The Cyber-Wars occur in 2526.
 * Unknown (mid-century) - By mid-century (probably well before), much of what was once the southern United States has sunk under the "Mississippi Sea"--probably a much-expanded Caribbean Sea. (BFBS: Home)
 * Unknown (mid-century) - Space travel is relatively commonplace and affordable, though trips can be lengthy. It is common practice to sedate passengers for the longer trips. (BFBS: Biology Lesson on Mal Oreille)
 * Unknown (mid-century) - The Sontarans and the Rutans take their war to Chelsea 426. The Doctor is able to stop the Rutans and the Sontarans leave before the colony collides with a Great White Spot. With help, the Doctor is also able to prevent this. (NSA: The Taking of Chelsea 426)
 * Unknown (late century) - Space travel appears to be significantly faster by the end of the century; the approximately 27,000 light-year trip between Earth, near the edge of the galaxy, and Dellah, near its core, takes about eleven months. (BNA: Oh No It Isn't!)
