The Hawaiian Kingdom, especially King Kamehameha The Great and King Kalakaua. I sadly know many that believe that the Hawaiian Islands were never a nation.

When in fact one has to wonder where they would be today if the united States didn't annex them. Kalakaua was the first King to circumnavigate the globe, and the iolani palace had electric lighting, and plumbing before the White House. There was even a point where hawaii boasted a higher literacy rate than the united States and Europe.

But, we'll never know now.

The Great Pig War:

A border war between the US and Canada (at the beginning still a British colony), which was triggered by the slaughtering of an American farmer's pig by a Canadian farmer who found it snacking on his potatoes. It is a conflict that involved several thousand armed men, including for a time the notorious Southern hothead George E. Pickett (later of Pickett's Charge), and which lasted for thirteen long years - yet which is rarely mentioned in the history books of any of those nations.

No shots were fired. Nobody was hurt. Shortly after its began, a lone Royal Marine was whacked in the eye by a rock hurled from the American position. He was shipped to Fort Victoria for treatment, lived to return to his station with sight intact, and is the only documented casualty of the entire conflict. For most of the time, the two sides spent their hours smoking, playing cards, and sneaking out to visit the other sides' lines, to swap navy rum purloined from the British Quartermaster, for tobacco and fresh American produce, which was scarce on the opposite side.

The site of the British main position, which today lies within the US' San Juan National Historical Park, is the only bit of non-diplomatic soil in America, over which the Union Jack is flown daily.

Easily qualifies as *The. Best. War. Ever.*

I think the Great Schism is overlooked a lot, and really funny. It starts with a single pope, then two others saying, "what the hell" declaring themselves pope, and all the while excommunicating each other.
