On June 3, 1989 at 22:20 local time, Grand Ayatollah Ruhollah Khomeini, the leader of the Iranian Revolution and the first Supreme Leader and Founder of the Islamic Republic of Iran, died in Jamaran, Greater Tehran, at the age of 89 after spending eleven days in a private hospital, near his home after five heart attacks in ten days. Sources put his age at 89 years old, and the cause of death is bleeding in the digestive system.
As a mark of respect, the Iranian government ordered all schools to close on Sunday, declared 40 days of mourning and said schools would be closed for five days. Pakistan has declared ten days of national mourning, Syria has declared seven days of mourning. Afghanistan, Lebanon and India have declared three days of mourning.
Khomeini was given a state funeral and buried at the Behesht-e Zahra (Zahra's Paradise) Cemetery in southern Tehran. It has been estimated that around 10 million people attended his funeral, one-sixth of Iran's population, the largest proportion of the population ever to attend a funeral procession, as well as one of the largest gatherings in human history.
In 1992, the construction of the Mausoleum of Ruhollah Khomeini on the burial site was completed.
