The Old Bajoran Republic was an interstellar governmental authority that existed in Earth's 4th century. Circa the year 370, the Bajorans battled a non-humanoid race called the Vorel, expanding their Republic as far as the Tarvo system. (TNG short story: "The Naked Truth")
- The DS9 episode: "Explorers" establishes the Bajorans used solar sail spacecraft as early as Earth's 16th century. The episode would also seem to suggest claims of Bajoran interstellar travel prior to the 16th century would be considered, at best, unproven.
