The An Lushan rebellion was a civil war in China that lasted from 755 to 763, at the approximate midpoint of the Tang dynasty (618–907).

City in Sicily, Italy
Palermo is the capital and largest city of the autonomous island region of Sicily in southern Italy, located on the eponymous gulf facing the Tyrrhenian Sea.

Duke of Burgundy from 1404 to 1419
John I was a scion of the French royal family who ruled the Burgundian State as the Duke of Burgundy from 1404 until his assassination in 1419. He played a key role in French national affairs during the early 15th century, particularly in his struggle to remove the mentally ill King Charles VI and during the Hundred Years' War against the Kingdom of England. A rash, ruthless and unscrupulous politician, John murdered Charles's brother, the Duke of Orléans, in an attempt to gain control of the government, which led to the eruption of the Armagnac–Burgundian Civil War in the Kingdom of France and in turn culminated in his own assassination in 1419.
