The kina of 9 Ab (lament) Yehudah veYisrael, was written by Don Judah Yahya, who fled to Portugal in 1391 and was employed in the service of Queen Philippa of Lancaster. When the preacher Vincent Ferrer sought to preach against the Jews in Portugal he was told by the king, at the instigation of Judah, that he could only do so with a red-hot crown on his head!
