The Nazi party
The Nazi party as a whole was not interested in the occult. A few high ranking members were quite obsessed with it, though. Among these high ranking party members the most prominent was Heinrich Himmler, the infamous SS commander-in-chief.
It’s widely renown that Hitler, who was a deeply materialistic character and did not believe in horoscopes, ghosts or anything supernatural, frequently and harshly reprimanded those hierarchs who "wasted their time" consulting astrologers or meditating around round tables.
A bit of history first. After the Nazi party came into power after the general election of 1933, an internal purge took place in 1934. Widely known as "The Night of the Long Knives" or "Operation Hummingbird" it resulted in the dessolution of the powerful SA corps and the death of its violent charismatic leader, Ernst Rohm. Heinrich Himmler and his SS carried out the operation quickly an efficently and, being regarded as much more political reliable than the SA, were given both a large share the SA confiscated properties and more resources as a reward.
The SS, a previous second-tier Nazi organization, found themselves flooded with money and resources almost overnight.
It would take many pages to describe the confounded beliefs of Himmler and his chief followers. Let’s just say that they included (but were not limited to) Madame Blavatski’s teachings about a superior race born in the mountains of Central Asia, the Arthurian and Nibelungen myths, the Germanic hero-kings of yore and much more.
With so much money at hand the SS went on a "spending spree" to finance whatever project they saw as related to their beliefs. They generously financed expeditions to the Himalayas to find traces of long-lost kingdom of Agarthi, gave enormous grants to cover any study they saw fitting in their twisted belief system… It has often been said that Himmler was obsessed with the occult in the same way as Goering was obsessed with wine and food, but we cannot say how much of this obsession was real, how much was cleverly calculated propaganda and how much a later invention.
There have been all kind of ridicolous legends about the Nazis and their involvment in the occult that it’s even hard to start. One of the most widely circulated is that when the Red Army pushed home the final assault on Berlin they were faced by a legion of Tibetan monks dressed in black SS uniforms. Another says that when Austria was annexed in 1935 the Nazi immediately took away the Holy Roman Empire regalia from the Hofburg because they wanted to get possession of the Holy Lance. The regalia translation was very real, but it had of course a clear political meaning and, moreover, the Holy Lance had already been shown to not be an ancient relic but a Medieval fake, and it’s probably a Frankish or Longobardic contus.
