Alexander I of Macedonia (1983: Doomsday)

Alexander I Karađorđević (Serbian Cyrillic: Александар I Карађорђевић; born 17 July 1945), was the last heir-apparent to the defunct throne of the Kingdom of Yugoslavia as the first and only child of King Peter II, and the first King of Macedonia.

Due to his father's exile from Yugoslavia in 1945, Alexander was born and raised in the United Kingdom, where he enjoyed close relationships with members of the British Royal Family. He was an advocate for monarchism throughout his life.

Alexander and his family survived the events of Doomsday in 1983 while living in the Spanish countryside. After the food supply was stabilized, they were able to find a boat still harbored and refueled it. Soon, a few more vessels were found and refueled and they set sail for the Karađorđević dynasty's homeland, Yugoslavia, where they planned to restore the monarchy and make Alexander king. They landed in what was once the Socialist Federal Republic of Yugoslavia after a couple of weeks and prepared to move into the former country, which had partially collapsed due to being in a weakened state after the destruction of Belgrade and strong nationalist sentiment in many parts of the country.

During the trek, Alexander and the Karađorđevićs were mistaken as Croatian rebels by Serbians soldiers which forced them to head down south. The Karađorđevićs arrived in Skopje, where the South-Eastern Theater agreed to help them established a military force, despite of low numbers. Alexander and his entourage was able to capture small parts of southern Serbia due to very little defence, and moved south to capture Skopje, where they set up an emergency capital city and moved westward to conquer more territory. After more men, food, and arms were captured they moved to take over a portion of the northern areas of what once made up the area known as Greek Macedonia.

By the end of the decade, Alexander had managed to gather up the people around a few major cities, and the creation of a strong, central, monarchy was announced to the Macedon public. However, the proposal was scrapped in favor of a constitutional monarchy due to local opposition.

In 1991, Alexander Karađorđević finally realized his dream and was crowned the first King of Macedonia.
