 While on a visit to the Peloponnese in 1862 a new coup was launched and this time a Provisional Government was set up and summoned a National Convention . Ambassadors of the Great Powers urged King Otto not to resist , and the king and queen took refuge on a British warship and returned to Bavaria aboard ( the same way they had come to Greece ) taking with them the Greek royal regalia which they had brought from Bavaria in 1832 . It has been suggested that had Otto and Amalia borne an heir , then the King would not have been overthrown , as succession was also a major unresolved question at the time . It is also true , however , that the Constitution of 1843 made provision for his succession by his two younger brothers and their descendants .
