were weakened during World War I. In 1915, Germany occupied western parts of the Russian Empire. After the Russian Revolution in 1917, Germany conceived the geopolitical strategy of Mitteleuropa – a regional network of puppet states that would serve as a buffer zone – and agreed to allow the Vilnius Conference, hoping that it would proclaim that the Lithuanian nation wanted to detach itself from Russia and establish a closer relationship with Germany. However, this strategy backfired; the conference, held on September 18–23, 1917, adopted a resolution that an independent Lithuania should be established and that a closer relationship with Germany would be conditional on Germany's formal recognition of the new state. On September 21, the 214 attendees at the conference elected a 20-member Council of Lithuania to codify this resolution. The German authorities did not allow that resolution to be published, but they did permit the Council to proceed. The Vilnius Conference also resolved that a constituent assembly be elected "in conformity with democratic principles by all the inhabitants of Lithuania".

The German representative, Kurt von Lersner, insisted that not one word be changed in the agreed-upon text and that all the Council members sign the document.

Fifteen voted in favor of the Act, three voted against it, one member abstained, and one did not participate. It is not entirely clear whether every member of the Council signed this document. The Act was written in German, and apparently no official Lithuanian translation was prepared. Therefore, different sources provide slightly different translations. The Act of December 11 pronounced Lithuania's independence, but also asked the German government for protection (clause 2) and called for "a firm
