Archduke John of Austria

He was sent to Paris as ambassador by imperial regent Archduke John of Austria, and was one of the deputation which offered the imperial crown to Frederick William IV. After the breakdown of the German parliament, Raumer returned to Berlin, where he was made a member of the House of Lords of Prussia.
