Editing Max Planck (section)

=== Post-war and the Weimar Republic ===
In the turbulent post-war years, Planck, now the highest authority of German physics, issued the slogan "persevere and continue working" to his colleagues.

In October 1920, he and [[Fritz Haber]] established the ''[[Notgemeinschaft der Deutschen Wissenschaft]]'' (Emergency Organization of German Science), aimed at providing financial support for scientific research. A considerable portion of the money the organization would distribute was raised abroad.

Planck held leading positions at Berlin University, the Prussian Academy of Sciences, the German Physical Society, and the [[Kaiser Wilhelm Society]] (which became the [[Max Planck Society]] in 1948). During this time economic conditions in Germany were such that he was hardly able to conduct research. In 1926, Planck became a foreign member of the [[Royal Netherlands Academy of Arts and Sciences]].<ref>{{cite web |url=http://www.dwc.knaw.nl/biografie/pmknaw/?pagetype=authorDetail&aId=PE00002335 |title=Max Karl Ernst Ludwig Planck (1858–1947) |publisher=Royal Netherlands Academy of Arts and Sciences |access-date=4 August 2015 |archive-url=https://web.archive.org/web/20150910170739/http://www.dwc.knaw.nl/biografie/pmknaw/?pagetype=authorDetail&aId=PE00002335 |archive-date=10 September 2015 |url-status=live }}</ref>

During the interwar period, Planck became a member of the Deutsche Volks-Partei ([[German People's Party]]), the party of Nobel Peace Prize laureate [[Gustav Stresemann]], which aspired to liberal aims for domestic policy and rather revisionistic aims for politics around the world.

Planck disagreed with the introduction of [[universal suffrage]] and later expressed the view that the Nazi dictatorship resulted from "the ascent of the rule of the crowds".<ref>
