Age of Winter

The Long Winter
The Long Winter (used as the name of the event), or Age of Winter (used as the name of the era), was a significant part of Narnian history lasting from 900-1000 in which Jadis, the White Witch, reigned as the tyrannical ruler of the country for 100 Narnian years. She possibly destroyed the Line of King Frank, that ruled Narnia, after it resisted for 2 years, though it continued in Archenland.

All of Narnia only saw the snowy season of winter during the entire century due to the dark magic produced by Queen Jadis to suppress the creatures of Narnia. One of the era's greatest expressions of sadness focused around the excessiveness of winter and yet the complete lack of Christmas, an important spiritual feast for most Narnians.

Though the human population of Narnia had seemingly dwindled during the Age of Winter, and possibly even become extinct due to unbearable human living conditions, the Narnian natives could not be motivated to revolution until a new generation of ruling humans would appear along with Aslan, the inspiratory Narnian guardian and savior.

Also some time during this age the Ettins and Giants in Ettinsmoor and in Wild Lands of the North became uncivilised and their intelligence and empire had somehow collapsed.

Winter Revolution
The Long Winter ended with the melting of the ice and snow at the return of Aslan and the arrival of the Pevensies.

These hope-bringing events, seen as favorable to the oppressed Narnians, ultimately drove them into rebellion against their unrightful Queen Jadis in the year-1000 Winter Revolution. The Narnians consequently established Aslan's Army, the first Narnian military force and were able to repel the Witch's Secret Police at the Battle of Aslan's Camp.

During the Battle of Beruna, the first large-scale battle that Narnia had ever seen, Jadis was killed by Aslan and her own army defeated. The Winter Revolution was immediately followed by the coronation of the Pevensies and the beginning of the Golden Age of Narnia.
