The mine was exhausted by 1885, so people from Moresnet had to find a new way to find money. Some wanted to start a casino, or issue their own stamps. Dr. Wilhelm Molly, wanted to change Moresnet into a country where everyone would speak Esperanto. He wanted to name the country Amikejo ("place of friendship"). None of these plans succeeded. Belgium and Prussia (which became a part of Germany in 1871) both wanted to take over the territory. In 1914, in the First World War, Germany invaded Belgium and occupied Moresnet. In 1915 they officially annexed it, so Neutral Moresnet did not exist any more.
