On the night of 14/15 August 1738, the future Frederick the Great, then Crown Prince, was initiated as a Freemason in Brunswick, being quickly passed to fellowcraft and raised to Master, all without the knowledge of his father.
He invited Baron von Oberg and the writer Jakob Friedrich von Bielfeld, who were instrumental to his candidature, to form La loge première/La loge du Roi notre grand maître at Rheinsberg Castle, with Oberg as Master.
When the King departed in the same year for the first Silesian War, La loge première was dissolved and its members joined the new lodge.
To escape the Masonic hostility of the Third Reich, they turned to the "National Christian Order Frederick the Great" to, but this had no effect, because in 1935 they had to dissolve.
After the Second World War, the Great National Mother Lodge was reactivated in 1946, but their effect area was initially limited to the American Sector in Berlin.
