Tajzadeh continued his education after the end of Iran-Iraq war in 1988 and in 1992 was put in charge of House of Iran in Paris. But a few months later, when Khatami resigned from the Ministry of Culture, he returned to Iran. He then had to abandon pursuing a PhD in political science when he joined Mohammad Khatami’s headquarters in the campaign for the 1997 presidential election, which led to victory for Khatami.
