The incumbent Emperor of Austenasia, Alexander VI ascended the Throne on 30 September 2025, having been appointed Heir to Aggelos I by the Senate.

Prior to being appointed Heir, Alexander – then known as Crown Prince Shiro – was a member of the Senate who also served in several Cabinet positions, the first in 2018. Appointed Princeps Senatus (chairman of the Senate) in April 2024, he played a vital role in advising and supporting Emperor Aggelos I during the latter’s reign.

Also serving as the head of state of Zenrax, where Alexander VI reigns as Shiro I, he oversaw friendly diplomatic co-operation between Austenasia and Zenrax from 2016 onwards, culminating in him being recognised as holding the rank of Caesar in November 2023.

Austenasian Monarchs are numbered in reference to all previous monarchs of the Empire’s many land-claims. Alexander therefore adopted the ordinal of “the Sixth” in reference to Alexander V of Macedon, the highest numbered Alexander to have ruled over what is now Austenasian territory (namely the Empire’s claims of Elmythia and Kaiomenia).
