Who in history, that we know of, got the most for the least?
The 1494 Treaty of Tordesillas divided the New World between Spain and Portugal along a meridian 370 leagues west of the Cape Verde islands, off the west coast of Africa. The geography of the New World was still largely a mystery, and the agreement ultimately gave almost the entirety of the New World, save for Brazil, to the Spanish. Despite this, the treaty was mostly honored by both countries.
There’s the (likely apocryphal) story of Natives selling Manhattan to the Dutch for a pile of beads and trinkets.
The US bought Alaska from Russia, gaining about 375 million acres at roughly 2 cents/acre.
The Louisiana Purchase netted the US approximately 512 million acres at under 3 cents/acre. It’s gotta be this, right?
Purchasing your brother’s birthright (inheritance of the family estate) for a mess of pottage (lentil stew) proved to be quite a good deal. (Gen. 25:29-34)
It may have happened, and it may have been worse than that.
James W. Loewen, author of revisionist history books, points out that the sale was also a fraud: The Dutch paid the money (or beads or whatever) to a tribe that didn’t own the land. The same may have happened with the Louisiana Purchase.
The land was “France’s to sell” in that no other polity recognized at the time as a nation-state claimed sovereignty over the territory (It would later take a US Supreme Court ruling to declare that the various indigenous tribes were in fact legal nations). In any case what the US was purchasing was France’s claim to the territory; so the rest is splitting hairs.
George Steinbrennner bought the New York Yankees in 1973 for $8.8-million. Forbes now lists the tean at $4.6-billion, a 500-fold increase. Who’da thunk the Yankees would ever be worth anything?
John Batman’s treaty with the Wurrundjeri for the land on which Melbourne now stands was a pretty good deal.
Controversial aspects of the treaty include, but are not limited to, the fact that the European participants had absolutely no legal authority to conclude treaties or agreements of any sort (though they were at least meeting with the correct indigenous representatives), the fact that they defaulted on their obligations almost immediately (the treaty called for an annual payment - probably never happened AFAIK) and of course the old question of whether the indigenous side were agreeing to the same thing the European side were agreeing to.
Settlement in Melbourne, or “Batmania” as they were calling it then exploded almost immediately, so I’m pretty sure various people in Batman’s group made out like bandits, though not so much Batman himself, since he kicked it only four years later
