Yazid I

Yazid I was the second Umayyad caliph, whose reign included the killing of Muhammad's grandson Husayn ibn Ali at Karbala. In 2010 the opening said: "His period witnessed the massacre of Kerbala, losses in North Africa, and a loss of supremacy at sea." Today the opening calls it "the death of Muhammad's grandson Husayn ibn Ali"; the word massacre survives once elsewhere in the article, not the opening. A reader today does not learn that the article once called the killing at Karbala a massacre rather than simply a death.

The opening as it read in 2010

Yazīd ibn Mu‘āwiya ibn Abī Sufyān (born July 23, 645; died 683), commonly known as Yazid I , was the second Caliph of the Umayyad Caliphate (and the first one by heredity), ruling for three years from 680 CE until his death in 683 CE.1 The period of Yazid's rule is thought of as a disaster for Muslims and his rule is still remembered by many, especially Shia Muslims. His period witnessed the massacre of Kerbala , losses in North Africa, and a loss of supremacy at sea. During this period, the spoilation and profanation of the holy cities of Makkah and Madinah by his forces occurred.2
