March 1667 CE
The international situation in 1667 is very advantageous for France.
Spain has already been at war with Portugal for some years (the Portuguese Restoration War), which has brought Spain almost only defeats and which has bound up the largest part of the Spanish military potential.
France had at first supported Portugal covertly, then openly.
Thus, the two states formally conclude an alliance on March 31, 1667.
