William of Tyre (c. 1130 – 29 September 1186) was a medieval prelate and chronicler. As archbishop of Tyre, he is sometimes known as William II to distinguish him from a predecessor, William of Malines. He grew up in Jerusalem at the height of the Kingdom of Jerusalem, which had been established in 1099 after the First Crusade, and he spent twenty years studying the liberal arts and canon law in the universities of Europe.
