1862, a coup overthrew the rule of Greek king Otto I and was recognized by Britain, Russia and France. The Greek National Assembly approved Prince Alfred, the second son of Queen Victoria of England (later Duke of Edinburgh and Duke of Saxony-Coburg-Gotha), as the king of Greece, hoping to get ionian islands through Britain. However, the London Treaty of 1832 stipulates that Britain, Russia and France cannot take their own royal family as the king of Greece. So Britain proposed Prince William of Denmark as the king of Greece, which was unanimously passed in the parliament of 1863 and declared as King George I of Greece.

There are two obvious differences between George I and his predecessor: first, he was chosen by the Greeks, not imposed on them; Second, he is a Greek, not just the king of the Greek kingdom. This shows that he is not only the king of the Greeks in the Greek kingdom, but also the king of the Greeks living in the territory that does not belong to the Greek kingdom.

1863 On March 30th, George I became the king of Greece, and the ceremony of George I's accession to the throne was held in Copenhagen. Former Greek Prime Minister Konstantin Kanas led the Greek delegation.

In the same year, 165438+ 10, 15, George I's father became king of Denmark, named Christian Ⅸ, who was the first king of the Gruxburg dynasty in Denmark [6]. It is rare for father and son to become the founding kings of two countries in the same year.
