It was during this time that al-Zawahiri allegedly met bin Laden and, finding much in common, the two soon forged a friendship and a strong alliance. According to the Center for Defense Information, al-Zawahiris Islamic Jihad and bin Ladens al Qaeda remained separate entities until 2001 when they were formally merged.
The pair became prominent in 1998 when they formed the World Islamic Front for the Jihad Against the Jews and the Crusaders, an organization whos principle goals were to eliminate all U.S. presence in Saudi Arabia, the U.N. embargo against Iraq and Israel's control of Muslim holy places in Jerusalem.

While analysts believe that bin Laden has the following and provided a large percentage of the funds that went towards the emergence of Al-Qaeda, al-Zawahiri is credited by the same experts as being the intellect and ideological driving force behind the organization.
It was he, they argue, who successfully merged al-Jihad with three other groups, including bin Ladens own forces, for the purpose of taking the fight inside the USA.
