Concept:The African Union was created to replace the weak Organisation of African Unity (OAU).
One African leader is widely recognized as the main driving force behind this change.

Libyan leader Muammar Gaddafi strongly pushed for a stronger continental body.
He proposed and championed the idea at the 1999 Sirte Summit in Libya.

Therefore, Gaddafi is the leader most credited for spearheading the AU's formation.
