- After a brief conflict the Lyrans and Hydrans settle their differences and the Lyrans join the Interstellar Trade Federation, established four months earlier. The ITF is the first treaty to unite all of the major powers in the Alpha and Beta Quadrants.
- Starbase 400, nicknamed "Versailles", is established in the Neutral Zone. It is manned by personnel from the Federation, the Romulan Star Empire and the Klingon Empire. It is the first sign of cooperation between the three since Nimbus III.
- The Romulan Empire enters a brief war with the Klingons, trying to expand its territory. This leads to tensions both in the ITF and on Starbase "Versailles" between the two powers.
