Arab Nationalist Movement
Pachachi completed his undergraduate studies in 1943 at the American University of Beirut in Lebanon, majoring in political science. While attending the university, he was inspired by the early emergence of the Arab Nationalist Movement on the campus. After his return to Iraq, his application for a job in the Ministry of Foreign Affairs was refused by the Iraqi Criminal Investigation Department due to his participation in the Kata'ib al-Shabab and support for the 1941 coup.
