'May have not been?'

He was a junior artillery officer when the Revolutionary Wars began and rose to general of division by merit, one French general among many.

As head of state he ended the Revolutionary Wars with the Treaty of Amiens, which came after the Treaty of Luneville after Austria was again defeated.

Great Britain broke the Treaty of Amiens and began the wars again.

Austria attacked Bavaria in 1805 and she turned to Napoleon for help. Prussia began the 1806 war and Russia kicked in as she did in 1805. Prussia was quickly defeated disastrously and Russia followed in June 1807.

Arguments can be made regarding Spain and Russia pro or con, but the idea that the wars were Napoleon's doing is just not historically correct.
