Queen Alia was Queen from Dec. 25th, I believe, 1972 until Feb. 9, 1977 when she was killed. Her preoccupations were with the disabled, women and children and overall health issues. Many projects in her name were/are chaired by KH's sister and a few now by Princess Haya (please correct me if I am getting her title wrong). Such was her commitment to women's issues, she attended a conference of ME women held in Egypt w/in 2 weeks of Prince Ali's birth. I read this in Jehan Sadat's memoirs.
She did make it clear family was first priority and had no official office anywhere, per Haya's recollection. She spent most of her time at home wearing jeans and a t-shirt saying "I Love Hussein." She did not shirk functions, royal engagements and state visits but her husband and children--and the kids were very young--were her focus and it is likely that, as they grew, she would have established an office and taken on more causes. Fascinating lady! And when I say she did not shirk her duties--well, she died trying to help solve an issue in Aqaba at a hospital where people were complaining their treatment was bad. She immediately flew off and her helicopter crashed on the way home in a sudden sandstorm. KH, in his video bio, mentioned there were 2 helicopters flying together. The one she was on crashed; but I never heard if the other did, as well.
