The Russian Revolution of 1917 caused Charles much concern and he watched anxiously during the ensuing power struggles between the left- and right-wing parties in Germany. On the morning of 9 November 1918, during the German Revolution the Workers' and Soldiers' Council of Gotha declared him deposed. On 11 November, his abdication was demanded in Coburg. Only on 14 November, later than most other ruling princes, did he formally announce that he had "ceased to rule" in both Gotha and Coburg. He did not explicitly renounce his throne but no longer had a right to rule.
