Yazid demands allegiance of Husayn

"Muawiyah dies and Yazid is appointed as his successor. Yazid in order to assure his kingship, needed the submission of influential people. He ordered the governor of Medinah to take the allegiances of Imam Husayn (AS) right away, and if he refuses, to kill him. The governor immediately sent a deputy to call Imam Husayn (AS). As soon as Imam Husayn (AS) came inside, the governor told him straight out, “You have to pay allegiance to Yazid.’’ Imam Husayn replied, “A person like me should not pay allegiance secretly. If you want, you can call all the people, in public, and ask everyone, and us with them, to have one voice.” The governor accepted, but his secretary Marwan warned him, “If he leaves you and does not pay allegiance now, you will not have power over him again. Put him in prison until he pays allegiance, or kill him.” Imam Husayn said, “Whoever of you kills me will be sinful and untruthful.” Then, to the governor, he said, “O governor! We are the People of the Prophet’s House, and we are descendants of the Prophet. Yazid is a drunkard who kills people without reason, and a person like me does not pay allegiance to a person like him. However, let us meet in the morning and let us see, you and us, who is most eligible for leadership.” After the incident the Imam visits garave of his grandfather and decids to leave Medinah for Mecca."
