In a letter to the Antarctic Micronational Union, Ludwig Brienović, former King Ivan Brienović, notified the Administrative-General about the dissolution of the Kingdom of Brienia. In compliance with Section III of the AMU Charter, the former delegates of the Kingdom of Brienia have been removed from all logs, registers, and forums, and an updated AMU Map will be released in brief.
The Kingdom of Brienia joined the AMU on 12 October 2020 and had a claim over Drygalski Island.
