“Persecution of Jews” [Almohad Empire; Present-day Morocco, Algeria, Libya, Spain, …] [Unconfirmed] 

Commentary from other sources:
1) Beginning of Jewish persecution in Almohad in northern Africa and Southern Spain; Jews flee or pretend to accept Islam. [The persecution could have been ordered by Caliph Abd al-Mu’min.]
