Imru' al-Qais
Legend has it that Imru' al-Qais was the youngest of his father's sons, and began composing poetry while he was still a child. His father strongly disapproved of this habit in his son, believing poetry to be an unseemly pastime for the son of a king. His father also disapproved of Imru' al-Qais' scandalous lifestyle of drinking and chasing women, and eventually banished him from his kingdom, or so the legend goes. But later, when the tribe of Asad rebelled and assassinated his father, Imru' al-Qais was the only one of his brothers to take responsibility for avenging his death. Renouncing wine and women, he fought the tribe of Asad until he had exacted revenge in blood, and spent the remainder of his life trying to regain his father's kingdom.
