Astro-Yemeni philosophy, or Yemeni Astronism, and also known as Yemeni Tanwir as part of the larger Tanwir’ism denomination, refers to the presence of Astronism in Republic of Yemen under management and philosophical jurisdiction of The Institution of The Philosophy of Millettism for the Republic of Yemen, a national subsidiary for the worldwide Astronist Institution. The Institution of the Philosophy of Millettism for the Republic of Yemen oversees the construction and maintenance of observatories and planetariums throughout its jurisdiction. Yemen is split into twenty-two governorates and is set to hold one Grand Observatory in the capital city of Sana’a. 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 Yemen. Astronism is not recognised as a religion in Yemen as of November 2019 and significant concerns have been raised regarding the religious liberties of Astronists in the country, thus the Astronist Institution has labelled the situation in Yemen as terminal, the lowest possible ranking of religious freedom. In November 2019, only 50 Yemenis were recorded as Astronists which forms an almost non-existent proportion of the country's total population. A combination of issues for the lack of dissemination of Astronism in Yemen are to blame, namely the high amounts of persecution of religious minorities as well as the lack of accurately translated Astronist materials into Arabic as of the end of 2019.
