Astro-Serbian philosophy, or Serbian Astronism refers to the presence of Astronism in the Republic of Serbia under management and philosophical jurisdiction of The Institution of The Philosophy of Millettism for the Republic of Serbia, a national subsidiary for the worldwide Astronist Institution. The Institution of the Philosophy of Millettism for the Republic of Serbia oversees the construction and maintenance of observatories and planetariums throughout its jurisdiction. Serbia is split into twenty-four districts and is set to hold one Grand Observatory in the capital city of Belgrade. This national branch of The Institution of The Philosophy of Millettism manages the official representation and depiction of Astronism throughout this territory, including efforts to protect the identity of the philosophy with the intention of further disseminating it throughout the territory. It is The Institution alone that is granted the status of proprietor to the philosophy in this territory as any other organisations or institutions proclaiming such a role are deemed as unauthorised proprietors and are therefore considered as part of the anti-Institutionist movement. History of Astronism in Serbia. As of November 2019, Astronism is not recognised as a valid religion or religious group in the country of Serbia. According to the Astronist Institution's late 2019 report called the Demographics of Astronism, Serbia had a population of 8,000 Astronists. Despite their unrecognised status, Astronists enjoy relative religious liberties in the country and can practice and profess their faith openly and publicly without fear of repression or incident. Therefore, the Astronist Institution has not expressed concerns regarding the religious freedoms for Astronists in this country. A significant barrier to the further spread of Astronism in the country is the lack of accurate translations of Astronist materials in the dominant language of the nation. As of late 2019, the Omnidoxy had not been translated into Serbian, the most widely spoken language of Serbia which remains an issue for Astronists living there.
