Bacco began her political career on Cestus as a representative for Pike City's Fifth District. In 2368, she was elected Governor of Cestus III, and served in that office for eleven years. During her term, she successfully dealt with a major population hike occurring as a result of an influx of refugees from former Federation worlds that had been conceded to the Cardassian Union in 2370. Five years later, the Cestus III government worked with the Federation Starfleet to repel an attempted Gorn invasion. Bacco was subsequently able to negotiate a historic peace treaty on behalf of the Federation with both the Gorn Hegemony and the Metrons; this achievement was particularly significant, as it was almost unheard-of for non corporeal entities to agree to enter into legal treaties with corporeal nations.
