Alexander VI was Pope from 1492 until his death in 1503. He was born Roderic Llançol i de Borja in the Kingdom of Valencia (modern Spain).
He was a very controversial figure. While he was highly skilled as a diplomat, politician and civil administrator, his Papacy was said to be characterised by libertinism and nepotism. There seems to be some truth in the allegations – he made his son, at the age of 17 and while still a student at Pisa, the Archbishop of Valencia.
