Hassan Rouhani was inaugurated as the president of Iran on August 4. He was elected in June, after mass mobilisations swept the country in support of his candidacy.
Those who supported him saw his election as the best way to open up space for reforms within the country. However, he is not an outsider to the system.
Rouhani was on Iran's nuclear negotiating team and was the country's top negotiator with the European Union on Iran's nuclear program from 2003 to 2009. He received official endorsement from Iran's supreme leader, Ali Khamenei, on August 3.
