On July 17, 1973 Mohammed Daoud Khan, a former prime minister and cousin of the king, overthrew the Afghan monarchy in a nearly bloodless coup while King Mohammed Zahir Shah was abroad, abolishing the throne, proclaiming the Republic of Afghanistan, and installing himself as its first president. Zahir Shah had left Afghanistan in late June 1973 for eye treatment in Europe, spending time on the Italian island of Ischia. In the small hours of July 17, forces loyal to Daoud, including a commando battalion and air force officers, and assisted by members of the Parcham faction of the communist PDPA such as Colonel Abdul Qadir, seized the royal palace, Kabul airport, and key installations.
Within hours, and without armed resistance, Daoud announced over Radio Afghanistan that the monarchy was ended and a republic established, denouncing the king's rule as corrupt and effete. Zahir Shah, unwilling to provoke bloodshed, abdicated from exile in August and remained abroad, chiefly in Italy, for nearly three decades. Daoud's republic ended in his own violent overthrow and death in the 1978 communist Saur Revolution.

The 1973 Afghan coup was led by Army General and prince Mohammad Daoud Khan against his cousin King Mohammad Zahir Shah on 17 July 1973, resulting in the establishment of the Republic of Afghanistan; Daoud led forces in Kabul along with chief of staff General Abdul Karim Mustaghni to overthrow the monarchy while the King was convalescing abroad in Ischia, Italy, assisted by officers from the Parcham faction of the PDPA including Air Force colonel Abdul Qadir.
Zahir Shah left Afghanistan for London via Rome on the morning of 25 June 1973 for treatment after injuring his eye and then went to the island of Ischia, and on the morning of July 17 Daoud Khan with several hundred army supporters launched the coup, ending the monarchy within hours and without any armed resistance, with Daoud announcing the new republic through Radio Afghanistan at 7 in the morning.
Despite being part of the Musahiban Barakzai dynasty, Daoud Khan abolished the monarchy and replaced it with a republic, declaring himself head of state, head of government, foreign minister, and head of the Army, and in a radio address called the coup a national and progressive revolution, calling the King's rule corrupt and effete and vowing to replace it with genuine democracy.
The 1973 coup ended the Musahiban dynasty's nearly 40-year reign and the constitutional monarchy of the 1964 constitution, with Daoud proclaiming the Republic of Afghanistan, supported by reformist army officers and tacitly backed by factions of the Marxist PDPA, and the overthrow disrupted Afghanistan's longstanding posture as a neutral buffer state and set the stage for the 1978 Saur Revolution that killed Daoud.
Fate coding: Zahir Shah was deposed while abroad and did not return, abdicating from exile in August 1973 and living in Italy for decades, matching the dataset's fled the country fate; he was not physically harmed and eventually returned to Afghanistan in 2002 as Father of the Nation, noted as later context. Coding note: the coup abolished the monarchy and founded the republic; the Parcham (PDPA) involvement led some to suspect a communist or Soviet hand, a question sources debate and which is recorded as contested rather than asserted. Arc forward: Daoud's republic was overthrown in the April 1978 Saur Revolution, in which he and his family were killed, beginning the communist era and the road to the Soviet intervention, all separate later dataset events.
