Odinia International  is an Odinist religious organization which has chapters mainly on the U.S. mainland and in the United Kingdom. It was founded in 2011, in the vicinity of Hawai`i Volcanoes National Park, by its current Allsherjargyðja, Seana Fenner, and its first services were held at the Kilauea Military Camp. One of the primary aims of this organization is the restoration of European religion, but there is also a focus on regaining or preserving free speech and religious rights for native European peoples.
In keeping with the ideal of the Nation of Odin , which is to say putting blood before nationality, all European spiritual traditions are included in this effort, such as Germanic, Celtic, Anglo-Saxon, Slavic, and some Greek and Roman material as well. There is a series of Odinist religion restoration videos being made on the Odinistpodcast Channel  which make note of, and at times incorporate, related legends and rituals that, in the view of the primary researcher, Seana Fenner, appear to have belonged to a time when the European tribes had a wider geographical range and more common religious beliefs. Not just Odin and the Aesir, but also the Vanir, are recognized and honored by this religious group.
One point of divergence from other similar organizations, which might be described as Germanic and neo-Pagan in nature, is that although Odinia International is, in essence, in this general category, its founder and members do not consider themselves to be neo-Pagan , but a continuous outgrowth of the Old Religion, that is to say, of ancient European Heathen religion. Seana Fenner, also known as “Odinia”, a proper noun for the Nation of Odin, has suggested that since the same people and Gods are still extant, providing the same sources of divine inspiration, the original religion still is very much alive. 
Odinia International has been at the epicenter of a number of battles for European and Odinist civil rights, in particular in regard to controversies with the United States Army, the Department of Interior, specifically Hawai`i Volcanoes National Park, the Hilo Herald Tribune, and a Hawaiian online events website, all of which have refused to advertise Odinist events for the Hawaiian headquarters and temple of Odinia International, known as Freyja Hof. The crux of the matter is that all of the organizations in question did advertise Abrahamic religious services, such as Christian or Jewish events, and other Pagan events that are not European, such as Hawaiian or Shinto events. This has led to the charge that the behavior of the National Park and military organization in question violates the first Amendment of the Constitution and the guarantee that the U.S. government shall not to establish a state religion. The official U.S Army Chaplain of Oahu, Colonel Peter Mueller, has ruled that there was indeed bias against Odinists and in favor of Christians on the part of the administrators of the K.M.C. Military Camp in Hawai`i, but the other cases, which involve slightly different legal issues, are still ongoing. 
The strongly pro-European focus of this group has led to some particularly vocal opposition by more universalist Heathenry at the other end of the philosophical spectrum, namely, those who believe that there is no such thing as race and that anyone of any ethnicity should be able to join Odinist and Asatru religious groups, and that not allowing anyone of any race to participate in European religion is racist. A prime example of this point of view is that of “Heathens United Against Racism“, a group whose title suggests it is opposed to racism, but which does not allow anti-Zionist posts on its pages. . The leader of Odinia International has publically responded by stating that Odinism is a tribal religion, much like the native Japanese religion, Shinto, or Native American religion, not a universalist religion like Christianity or Islam, and that since universalism is Christian rather than Pagan, there can rationally be no such thing as a universalist Odinist. She maintains that universalist Heathenry is not truly Pagan at all, but instead, a hybrid Pagan-Christian religion.  
Odinia International also is known for its sacred family tree restoration project . This initiative is based upon traditions of ancient European Pagan communities and individual families having had holy trees which served as conduits for worship of European Heathen Gods . It is their wish to rebuild a network of sacred trees and other Odinist holy sites and temples in order to enhance the practice of Odinism for European folk worldwide.
Various articles and videos with new and original research on the topic of Odinism created by this organization can be found on a page called “Gods, Heroes, and Festivals“. and the Odinist Journal Foxfire put out annually by this organization has an online archive. . The latest initiative of Odinia International is a heavily censored, controversial news program called “Nation of Odin News“.
