Muawiyah also declared his son, Yazid, as his successor in [[Hasan–Muawiya treaty|breach of a treaty with Hassan]], Muhammad's grandson. Another of Muhammad's grandsons, [[Husayn ibn Ali]], would be killed by Yazid in the [[Battle of Karbala]]. Further Shia Imams, [[Ali ibn Husayn Zayn al-Abidin]] would be killed at the hands of ruling Umayyad caliphs.
