The reason for this is because directly after the end of turn 1, all Bavarian units are disbanded, including its Armed Citizenry, causing all of its former regions to be completely defenceless the region transfers to France, but is immediately taken over by the besieger. If any Bavarian regions during the Campaigns of the Coalition are under siege by the end of turn 1, these regions automatically transfer to the besiegers at the beginning of turn 2, and the besieging victors receive a diplomatic penalty with France for territorial expansion. This doesn't happen in either the Europe campaign for France or multiplayer campaigns, however.

In the Campaigns of the Coalition, Bavaria automatically merges with the French Empire by the second turn. Prussia requires Bavaria as part of its victory conditions. If left to its own devices, the A.I usually has Austria or Russia attack Bavaria early in the campaign. It's a good candidate for invasion, particularly for Austria, due its proximity to Austrian lands. The region of Bavaria itself is quite large, with a two-slot city, a factory building slot, a cultural building slot, and timber resources. It is one of France's many allies and is aligned against the coalition of France's enemies. It borders Austria to the east, Austrian-held Tyrol to the south, the Swiss Confederation to the south-west, Baden-Württemberg to the west, Hessen to the north-west, Saxony to the north, and Austrian-held Bohemia to the north-east.
