As King Hussein was undergoing cancer treatment in mid-1998, the King assigned Crown Prince Hassan a range of powers and authority to act as regent. With his newly gained powers, Hassan exercised a number of steps to consolidate his position as heir and future king, which included: (1) "orchestrating the removal of the [unpopular] government" of Abdelsalam Majali and appointing former Royal Court chief Fayez al-Tarawneh in his place, (2) organizing dialogue and reconciliation with opposition groups, most prominently the Muslim Brotherhood, and (3) attempting to effect changes at the top of the military. Hassan's attempted changes to the top hierarchy of the military angered King Hussein and led him to resume full duties as king. It is also a commonly cited reason for Hassan's removal as crown prince on 24 January 1999. Hassan's removal took shape through a 14-page typed letter, described by American historian W. Andrew Terrill as "extremely harsh", in which King Hussein expressed "unmistakable disappointment in Crown Prince Hassan" and ordered his replacement with Hussein's son Abdullah. Terrill describes King Hussein as perhaps having felt that Hassan had "interest in shifting the line of succession to his own family", which led to his dismissal as Crown Prince three weeks before Hussein's death.

He has served as the president of the Club of Rome from 1999 to 2007, the board of directors for the Center for Peace Studies and Conflict Resolution at the University of Oklahoma, the Parliament of Cultures, the Royal Jordanian Polo Club, and the International Tolerance Foundation for Humanities and Social Studies, and is honorary president of the Euro-Mediterranean Association for Cooperation and Development since 2012.

Prince Hassan has been a very active participant in Jordanian and International civil society. He founded the Royal Scientific Society in 1970, the Annual Bilad Al-Sham Conference in 1978, and the Royal Aal al-Bayt Institute for Islamic Thought in 1980. He has also established the Al al-Bayt University in Mafraq, the Hashemite Aid and Relief Agency, the Islamic Scientific Academy, the Triannual Conferences on the History and Archaeology of Jordan, the Amman Baccalaureate School, and the Al-Hassan Youth Award. He founded and chairs the Independent Bureau for Humanitarian Issues, Independent Commission on International Humanitarian Issues, the Higher Council for Science and Technology, the Royal Institute for Inter-Faith Studies, the Foundation for Intercultural and Interfaith Research and Dialogue, the Arab Thought Forum since 1981, the Kawakibi Democracy Transition Center, and the West Asia – North Africa Forum (WANA Forum), and was chair of the Policy Advisory Commission for the World Intellectual Property Organization from 1999–2002.

In 1968, Prince El Hassan married Sarvath Ikramullah, daughter of Pakistani politician and diplomat Mohammed Ikramullah, and female Pakistani-Bengali politician, diplomat and Urdu author, Begum Shaista Suhrawardy Ikramullah. They first met in London in 1958, when they were both youngsters, and have four children together:

In 1965 Hassan was named as Crown Prince of Jordan after the constitution was amended. He was frequently regent during his brother's absences from the country. During Hussein's final illness in January 1999, he was replaced by his nephew Abdullah three weeks before the king died. Abdullah subsequently inherited the throne of Jordan.

Prince Hassan bin Talal (Arabic: الحسن بن طلال, born 20 March 1947) is a member of the Jordanian royal family who was previously Crown Prince from 1965 to 1999, being removed just three weeks before King Hussein's death.
