After earning his B.A. with first-class honors in Oriental Languages at Trinity College, Cambridge, he was offered a scholarship to Tehran University in Iran, where he planned to work for his Ph.D. He then moved to Cambridge and defended his thesis in 1965. Algar wrote his Ph.D. on the political role of Shi'a religious scholars in the 19th century. Algar met with Khomeini in exile in Paris and on brief occasions in Iran after the revolution there in 1979. He translated selected writings and speeches of Khomeini for Islam and Revolution, and also gave his own account, The Roots of the Islamic Revolution in Iran. He considers the Iranian revolution "the most significant, hopeful, and profound event in the entirety of contemporary Islamic history." He received his formal training in Islamic studies at Cambridge University. In Berkeley he taught courses including tafsir, Sufism, Shi'ism, the history of Islam in Iran, Arabic, Persian and Turkish literature. Algar is the author of more than 100 articles in the Encyclopedia Iranica. In regards to his conversion to Islam, Algar has said, "I don't look like the average person's idea of a Muslim."
Views and scholarly critiques
Algar is described as "a seasoned scholar who knows his Islamic theology and modern Middle Eastern history". According to Algar, Wahhabis lie outside the wide orbit of Sunni Muslim orthodoxy. Algar criticizes the Saudi regime for supporting them as he believes the Wahhabism fed into movements such as the Taliban. He similarly charges United States for backing the Arabian Peninsula climate over the years. While his work on the political role of Shi'i clerics has been said to be 'an outstanding study of one of the most interesting periods of Iranian history', some sources find Hamid Algar's explanations of complex events on the theoretical plane as simplistic. Ervand Abrahamian refers to Algar's biography of Mirza Malkum Khan as "highly readable, well documented, and definitive" pointing out Algar's "meticulous scholarship". He does, however mention some of Algar's "minor" flaws in that work. Algar's translation of Arabic poetry has been described as a sensitive one which "often achieves a beauty and conviction equal to the original poem". He caused a public incident in April 1998, during an on-campus commemoration of the Armenian Genocide organized by the Armenian Students' Association, when he allegedly said that Armenian genocide never happened and made other controversial remarks. A subsequent complaint prompted the university to carry out an investigation. In January 1999, the five-month-long investigation concluded and found that while Professor Algar's comments "seem to fall within the bounds of constitutionally protected speech", it did not mean that "the University condones the type of speech used by the parties." The Complaint Resolution Office did, however, issue an apology to the students on behalf of the university. Not satisfied with the university's response, the students turned to the Associated Students of UC Berkeley, which unanimously passed a resolution entitled "A Bill Against Hate Speech and in Support of Reprimand for Prof. Algar" on March 10, 1999.
