After Breaking, often abbreviated AB for historical purposes, was a period of time following the Breaking of the World which lasted for roughly 1,350 years. During this time, man rebuilt its civilization which had been destroyed by male Aes Sedai who had gone mad. Due to the events leading up to the Breaking of the World, trust was always in short supply, the Ten Nations that controlled the majority of the Westlands emerged from the Breaking.
This era of time lasted until the fragile peace of the new age was shattered by the onslaught of the Trolloc Wars. After the Trolloc Wars ended, the massive amount of lost records resulted in a debate over exactly what year it was under the After Breaking system. This confusion was the reason for the replacement of this system with that of the Free Years.
