Those who do not learn from the mistakes of history are doomed to repeat them, and so we have studied what little material exists about attempts at seastead-like ventures. We find some of the following quite illustrative. Note that the distinction between "attempted" and "proposed" (the next category) is somewhat arbitrary. Since most nation-founding attempts don't get past the drawing board, our standards for what constitutes an attempt are fairly low. Also, some of these attempts are still ongoing.
