Despite his distaste for German, Frederick did sponsor the ' (Royal German Society), founded in Königsberg in 1741, the aim of which was to promote and develop the German language. He allowed the association to be titled "royal" and have its seat at the Königsberg Castle. However, he does not seem to have taken much interest in the work of the society. Frederick also promoted the use of German instead of Latin in the field of law, as in the legal document ("Project of the Frederickian Body of Laws"). which was written in German with the aim of being clear and easily understandable. Moreover, it was under his reign that Berlin became an important center of German enlightenment.
