A micronation isn’t a particularly grandiloquent web site based on a Japanese action figure line. It’s actually a tiny country. Really tiny. Take for example the short-lived Republic of Minerva:
The Republic of Minerva was set up in 1972 as a libertarian new country project by Nevada businessman Michael Oliver. Oliver’s group conducted dredging operations at the Minerva Reefs, a shoal located in the Pacific Ocean south of Fiji. They succeeded in creating a small artificial island but their efforts at securing international recognition met with little success and near-neighbour Tonga sent a military force to the area and annexed it.
Oh, and there are instructions for creating your own.
(Do you remember a time when people just collected stamps if they had too much time on their hands?)
