|Founded at||Godstone, Great Anglia|
The organisation was founded in support of Great Anglia and Suverina during the Anglian War. This was the result of a previous meeting by Anglian officials with representatives from Noble Nykia, Afropa, Abantium, Norrium, and Yien. Though the contents of the meeting remain unknown, unconfirmed details regarding a possible military alliance began to leak. The OCA was founded in the Anglian capital of Godstone on 15 May 2021. At the signing ceremony these signatories were joined by a representative from the State of Alshamal, after a military coup removed Grand Vizier Mamadou bin Sambo from office, and the figurehead King appointed a new Anglian friendly Grand Vizier.
