Otto of Greece
Otto was also an absolute monarch and never agreed to make Greece a constitutional monarchy as he was apparently a strong believer of absolutism. All of the bad things that Otto did in Greece made him highly unpopular and that the Greeks eventually overthrew him. Otto lived the remaining 5 years of his life in exile at his home country of Bavaria until he died in 1867 at the age of 52. When he was on his deathbed, Otto regretted treating the Greek people very bad. His last words were "Greece, my Greece, my beloved Greece!!!".
