Diocletian
Roman Emperors Diocletian and Maximian appoint Galerius as Caesar to Diocletian, beginning the period of four rulers known as the Tetrarchy.
Roman emperor from 284 to 305
Diocletian, nicknamed Jovius, was Roman emperor from 284 until his abdication in 305. He was born Diocles to a family of low status in the Roman province of Dalmatia. As with other Illyrian soldiers of the period, Diocles rose through the ranks of the military early in his career, serving under Aurelian and Probus, and eventually becoming a cavalry commander for the army of Emperor Carus. After the deaths of Carus and his son Numerian on a campaign in Persia, Diocles was proclaimed emperor by the troops, taking the name "Diocletianus". The title was also claimed by Carus's surviving son, Carinus, but Diocletian defeated him in the Battle of the Margus.

John_VI_Kantakouzenos
Coronation of John VI Kantakouzenos as Byzantine Emperor by patriarch Isidore I of Constantinople at the Church of St.
Mary of Blachernae.
John VI Kantakouzenos or Cantacuzene was a Byzantine Greek emperor and nobleman, statesman, and general. He served as grand domestic under Andronikos III Palaiologos and regent for John V Palaiologos before reigning as Byzantine emperor in his own right from 1347 to 1354. Deposed by his former ward, he was forced to retire to a monastery under the name Joasaph Christodoulos and spent the remainder of his life as a monk and historian. At age 90 or 91 at his death, he was the longest-lived of the Roman emperors. His two disastrous civil wars led to the loss of much of the remaining territory in the Balkans under Byzantine control to the Serbian and Bulgarian empires, but the most severe loss during his civil war was the loss of the Gallipoli peninsula to the Ottoman Turks, allowing the Ottomans to gain territory in Europe and setting the stage for the destruction of the Byzantine Empire a century later.

James_I_of_Scotland
Coronation of James I of Scotland at Scone.
King of Scots from 1406 to 1437
James I was King of Scots from 1406 to 1437. The youngest of three sons, he was born in Dunfermline Abbey to King Robert III and his wife Annabella Drummond. His older brother David, Duke of Rothesay died under suspicious circumstances while being detained by their uncle, Robert, Duke of Albany. His other brother, Robert, died young. Fears for James's safety grew through the winter of 1405/6 and plans were made to send him to France. In February 1406, James was forced to take refuge in the castle of the Bass Rock in the Firth of Forth after his escort was attacked by supporters of Archibald, 4th Earl of Douglas. He remained there until mid-March, when he boarded a vessel bound for France. On 22 March, English pirates captured the ship and delivered the prince to Henry IV of England. The ailing Robert III died on 4 April, and the 11-year-old James, now the uncrowned King of Scotland, would not regain his freedom for another eighteen years.
