Has the AI ever offered you a ceasefire?

[Olaf The Great]

As the Sweboz I recruited two armies(one german one made up of mercenaries) and sacked and pillaged all of Gauls cities, both rebel and Aedui/Arverni. Managing to wipe out the Arverni and destroy all of the settlement's buildings and letting them rebel(the Arverni ones just went rebel, while the Aedui got most of the settlements.

After I sacked Venetio and Mediolanum I returned to Gernany and, just to see if it would work, asked the Aedui for protectorateship.

They..accepted.

First time that ever happened.

Oh and they have 2 FMs left :)
