The Arab Ba'ath Party's first congress was held in Damascus in 1947. Aflaq took the pre-eminent position of "Amid", sometimes translated as 'doyen' or as 'leader'; and was elected to a four-member executive committee. Under the constitution adopted at the congress, this made him effective leader of the party, with sweeping powers within the organisation; al-Bitar was elected Secretary General of the National Command. Zaki al-Arsuzi, the leader of the Arab Ba'ath, was not given any position, or membership in the party. Aflaq as "Amid" was responsible for ideological affairs and became the party's mentor, while al-Bitar controlled the party's day-to-day management. The merger would prove problematic, several members of the al-Arsuzi-led Ba'ath Party were more left-leaning, and would become, later in Aflaq's tenure as leader, highly critical of his leadership.
