In short
In 1046, Norman adventurers from northern France began seizing territory across southern Italy, exploiting local political fragmentation. Over the next century, these independent conquerors would consolidate their gains into a unified kingdom that reshaped Mediterranean politics and culture.
How it unfolded.
