Hitler's symbol was hooked cross (Haken Kruez), not Swastika

It is a common misconception that Hitler used the Swastika symbol. But Hitler himself never used the word "Swastika" to refer to his symbol. He called it “Hooked Cross”(“Haken Kreuz”).

Hitler first saw the Hooked Cross symbol in a Christian monastery (Lambach Abbey) which he attended as a boy. He later adopted it as an emblem for his party. There is no evidence that he ever heard of the word “Swastika”. Hooked Cross had been a sacred symbol of Christianity since its inception in ancient days and it is very natural to find Hooked Cross symbol in old churches and chapels.

The hooked cross was seen as a Christian symbol in Nazi Germany. Hooked cross had nothing to do either with Hinduism or Swastika. It existed as an important symbol of Christendom since its very existence. It was found on early Christian Graves of Rome in 2rd century CE.

If you were to go through the English translations of Mein Kampf (“My Struggle” an autobiography of Hitler”), you would find the mention of Swastika. Mein Kampf was translated into English by James Murphy, an English Christian Priest.

The English evangelists were opponents of Nazis and they tried to portray Hitler as a Pagan. The word Hooked Cross was conveniently translated as Swastika. When Hitler became extremely unpopular, the Evangelist lobby associated the Hooked Cross with Swastika to hide the fact that Nazism originated in Christian Socialism

The Nazi hooked-cross was generally tilted 45 degrees from the horizontal and always oriented in the "S" letter direction for their "socialism" whereas Swastika sits flat to the base.
