Austenasia and the Empire of Ovrestlia entered formal diplomatic relations with a treaty signed on 10 September 2020, following negotiations that began earlier that year. In exchange for Austenasian recognition, Ovrestlian monarch Thomas Marios I agreed to use the title “Hegemon” rather than “Emperor” in communications with Austenasia, and to cede an area of land to the Empire; this resulted in the cession of Kaiomenia on 5 October 2020, which Thomas Marios I now administers for Austenasia as Governing Commissioner.
- Status: Treaty of mutual recognition
- Relations established: 10 September 2020
