In 1985, the AXA brand is born, thanks to Claude Bébéar's actions.

For previously-named Mutuelles Unies / Drouot Group, the leader of private insurance in France at the time, this new name reflects a powerful ambition: Develop on an international scale.

30 years later, AXA is the world's leading insurance brand.

Faithful to the original ambition that led it to become the world's leading brand, AXA Group is committed to creating value while earning the confidence of its customers every day through innovation and engagement with the world.
