John II Komnenos
John II Komnenos or Comnenus ("Iōannēs II Komnēnos"; 13 September 1087 – 8 April 1143) was Byzantine emperor from 1118 to 1143.
Also known as "John the Beautiful" or "John the GoodKaloïōannēs"), he was the eldest son of Emperor Alexios
I Komnenos and Irene Doukaina and the second emperor to rule during the Komnenian restoration of the Byzantine Empire.
John was a pious and dedicated monarch who was determined to undo the damage his empire had suffered following the battle of Manzikert, half a century earlier.
John has been assessed as the greatest of the Komnenian emperors.
In the course of his twenty-five year reign, John made alliances with the Holy Roman Empire in the west, decisively defeated the Pechenegs, Hungarians and Serbs in the Balkans, and personally led numerous campaigns against the Turks in Asia Minor.
John's campaigns fundamentally changed the balance of power in the east, forcing the Turks onto the defensive and restoring to the Byzantines many towns, fortresses and cities right across the Anatolian peninsula.
In the southeast, John extended Byzantine control from the Maeander in the west all the way to Cilicia and Tarsus in the east.
In an effort to demonstrate the Byzantine ideal of the emperor's role as the leader of the Christian world, John marched into Muslim Syria at the head of the combined forces of Byzantium and the Crusader states; yet despite the great vigour with which he pressed the campaign, John's hopes were disappointed by the evasiveness of his Crusader allies and their reluctance to fight alongside his forces.
Under John, the empire's population recovered to about 10 million people.
The quarter-century of John II's reign is less well recorded by contemporary or near-contemporary writers than the reigns of either his father, Alexios I, or his son, Manuel I.
In particular little is known of the history of John's domestic rule or policies.

Charles Martel of Anjou
Charles Martel (8 September 1271 – 12 August 1295) of the Angevin dynasty was the eldest son of king Charles II of Naples and Maria of Hungary, the daughter of King Stephen V of Hungary.
The 18-year-old Charles Martel was set up by Pope Nicholas IV and the ecclesiastical party as the titular King of Hungary (1290–1295) as successor of his maternal uncle, the childless Ladislaus IV of Hungary against whom the Pope had already earlier declared a crusade.
He never managed to govern the Kingdom of Hungary, where an agnate of the Árpád dynasty, his cousin Andrew III of Hungary ruled at that time.
Charles Martel was, however, successful in asserting his claim in the Kingdom of Croatia, then in personal union with Hungary.
Charles Martel died of the plague in Naples.
His son, Charles (or Charles Robert), later succeeded in winning the throne of Hungary.
Charles was apparently known personally to Dante: in the "Divine Comedy", the poet speaks warmly of and to Charles's spirit when they meet in the Heaven of Venus (in "Paradiso" VIII).
