Second Age Flag of Gideon

One of those was the Creation of the Gideon Province

After the invasion was repulsed, Cyrodiil was in ruins. The only areas not completely destroyed by the invasion were badly damaged. Combined with the dramatic reshaping of the geography, creation of the Heartland Cliffs, destruction of the Imperial island, and erosion of the Nibenay Basin into what is now the Nibenay Islands caused a rift in the remaining population of Cyrodiil.

This combined with the fact the near decimation of Elsweyr, Blackmarsh and Morrowind created a major influx of refugees, changing the population demographics so drastically that new Province boundaries were required.

Anvil and Kvatch were moderately damaged in the west, while the only surviving city in the east, Bruma, was left in ruin. That along with a large population of Khajit refugees in the west, and a large population of Argonians in the east created great amount of resentment, which eventually led to a call for division. 

Gideon was created in the South with the newly named city of Hist.
