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. (BFBS: 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. (DW: Frontier in Space, K9TV: The Korven)

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

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

Major Events

 * Unknown (Early Century) - The Second Dalek War took place. Numerous planets were destroyed in the conflict. The war was stopped when the Tenth 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 had sunk under the "Mississippi Sea"--probably a much-expanded Caribbean Sea. (BFBS: Home)
 * Unknown (mid-century) - Space travel became relatively commonplace and affordable, though trips can be lengthy. It became common practice to sedate passengers for the longer trips. (BFBS: 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. With help, the Doctor prevented this as well. (NSA: The Taking of Chelsea 426)
 * Unknown (late century) - Space travel appeared 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, took about eleven months. (BNA: Oh No It Isn't!)
