Until the dissolution of the Empire in 1806, Liechtenstein remained a part of it, which accounts for the historical depth and closeness of German-Liechtenstein relations.

[2] In 1806 Liechtenstein gained its sovereignty, but as a member of the Confederation of the Rhine it maintained intensive contacts with the German states.

[3] In the post-war period, the principality broke away from Austria and concluded a customs treaty with Switzerland.

This act was justified by "questionable basic principles of the rule of law",[12] but the German media assume that this was an expression of the Princely House's disgruntlement.

[13] In 2008, the reigning Prince of Liechtenstein Hans-Adam II used the expression of a "Fourth Reich" in a letter about German-Liechtenstein relations.

In addition, he described the relations between the two countries as a "rollercoaster ride" and commented that they hoped for "better times" in this regard.
