Drahvin subjugation of Tivoli
From Tardis Wiki, the free Doctor Who reference
On 17 November 2900, the Drahvins subjugated the planet Tivoli and eradicated the Shakri. They were welcomed as heroes by the native Tivolians. The Drahvin subjugation of Tivoli eventually ended when they were chased off by the Hath, who were likewise welcomed as heroes as they laid siege to Tivoli on 8 December 3001.
