This timeline is my attempt at creating an entirely different POD for the Napoleonic wars to end peacefully.
The point of Divergence is the Battle of Galway. OTL, this battle never occurred. However, during the war of the Third Coalition, TTL Napoleon was struck by inspiration. The French Directory's attempt at inspiring revolution in Ireland had failed with the crushing of the Republic of Connaught. Napoleon saw Britain as his greatest enemy; although Europe nearly his, with the Holy Roman Empire disintegrating and his enemies scattered, Britain had held out against him since the original French Revolution and continued to levy more states to oppose him. The Battle of Galway was a naval and land battle; Napoleon's forces succeeded in breaking Britain's navy and gaining access to Britain's weak flank. Ireland fell to Napoleon's revolutionary forces, and Britain was forced into a grudging peace.
When the Third Coalition fell apart, Napoleon was the undisputed master of Europe. The Pope was even forced to grant him the title Emperor of the Romans, although after his death this title was withdrawn. The world was set for an entirely different development....
