Ireland

During the Easter Rising in Dublin in 1916, some republican leaders, including Patrick Pearse and Joseph Plunkett, contemplated giving the throne of an independent Ireland to Prince Joachim.
While they were not in favour of a monarchy per se, Pearse and Plunkett thought that if the rising were successful and Germany won the First World War, an independent Ireland would be a monarchy with a German prince as king, like Romania and Bulgaria before it.

The fact that Joachim did not speak English was also considered an advantage, as he might be more disposed to learning and promoting the use of the Irish language.
Georgia

After Georgia's declaration of independence following the Russian Revolution of 1917, Joachim was briefly considered by the German representative Friedrich Werner von der Schulenburg and Georgian royalists as a candidate to the Georgian throne.
Marriage
Prince Joachim married Princess Marie-Auguste of Anhalt (10 June 1898 – 22 May 1983), the daughter of Eduard, Duke of Anhalt and his wife Princess Luise of Saxe-Altenburg (daughter of Prince Moritz of Saxe-Altenburg), on 11 March 1916. The couple had one son, the Prince Karl Franz Josef Wilhelm Friedrich Eduard Paul (Potsdam, 15 December 1916 – Arica, Chile 22 Jan 1975).
Later life
After his father's abdication, Joachim was unable to accept his new status as a commoner and fell into a deep depression, finally committing suicide by gunshot on 18 July 1920 in Potsdam. One source reports that he had been in financial straits and suffered from "great mental depression". His own brother Prince Eitel Friedrich of Prussia commented that he suffered from "a fit of excessive dementia". Before his death, the couple had recently divorced. The direct causes are not really known to the public, only that there had been no previous report of marital troubles before the divorce was announced. Regardless of the reasons, this event may have also contributed to his depression.
Children and grandchildren
The only issue of the marriage of Prince Joachim and Princess Marie-Auguste was their son, Prince Karl Franz Josef Wilhelm Friedrich Eduard of Prussia (15 December 1916 Potsdam, Germany – 22 January 1975 in Chile).
On 5 October 1940, Prince Karl married Princess Henriette Hermine Wanda Ida Luise Schönaich-Carolath (25 November 1918 – 16 March 1972). They divorced on 5 September 1946. They were the parents of three children:
After the divorce, Prince Karl married, morganatically, Luise Dora Hartmann (5 September 1909 Hamburg, Germany – 23 April 1961 Hamburg, Germany) on 9 November 1946. The childless couple divorced in 1959.
Prince Karl's last marriage was to Doña Eva Maria Herrera y Valdeavellano (10 June 1922 Lima, Peru – 6 March 1987 Lima, Peru) on 20 July 1959 in Lima, Peru. They were married until Prince Karl's death and had two daughters;
