A.k.a. “Napoleon's Victory” or “Pax Gallica”. Written by Zach.
What if in 1807, the French invasion of Portugal is a tremendous success partly due to Spanish aid? The PoD of Pax Napoleonica is Napoleon's decision not to invade Spain. There is no Peninsular Campaign and in fact, France and Spain sign a treaty of friendship on the Third of May, 1808 (a reference to a famous Goya painting of the same title). With Iberia allied to France, Europe is under the control of Napoleon I. This leads to a very different outcome of the Napoleonic Wars… The timeline has currently reached the early-to-mid 1970s.
