Likewise, does the German royal family still exist?
Short answer: No. Germany hasn't had a royal family or monarch since the end of World War I, when Kaiser Wilhelm II abdicated the German and Prussian thrones. Since there was no agreement made on his successor, which would have been his son, Crown Prince Wilhelm, Germany became a de facto republic on November 9, 1918.
Likewise, who was the last king of Germany? Wilhelm II
Similarly one may ask, what ended the German monarchy?
Germany's monarchy was abolished in 1918 at the end of World War I and the abdication of Kaiser Wilhelm II. After giving up the German throne, he fled to the Netherlands and spent the rest of his life there in relative obscurity.
What happened to the German royal family after 1918?
Though long out of power, the German aristocracy still exists. The legal privileges of noble families were abolished with the founding of the Weimar Republic in 1919, but most were able to keep at least some of their estates, including castles, forests and large stretches of agricultural land.
