There are no countries in Antarctica, however, several countries have "claimed" territory for their own in the past, though for the most part these claims are largely symbolic and the continent is treated as a nature preserve by the international community. Mostly, those claims are not recognized internationally, and the United States does not recognize any of them. The countries of Chile, Argentina, France, the United Kingdom, Norway, Australia, and New Zealand have all made claims on Antarctica.
The United States Government has not claimed any land in Antarctica, though it has reserved the right to do so in the future (as has Russia). Large parts of the Antarctic coast and interior were first observed by American (U.S. Navy) sea captains and American aviators. In fact, the part of Antarctica called "Wilkes Land" was the first part of the Antarctic mainland that were ever seen, and it was named for Capt. John Wilkes of the U.S. Navy, the commander of the first ship to discover that seacoast. Other parts of Antarctica were first seen from airplanes commanded by Capt. Richard E. Byrd of the U.S. Navy. Byrd always had one or more crewmen on his flights, including his main pilot.
The leaders of the land exploration of Antarctica came from the United Kingdom(Shackleton and Scott) and Norway(Amundsen).
The two countries that are smaller in land area than Antarctica is Australia, and Europe
Australia and Europe
There are many countries that are smaller than Ireland. Luxembourg and Belgium are two examples of countries that are smaller than Ireland.
The two smallest continents are Australia and Europe. Australia is an island continent, however, Europe is not. Antarctica is the third smallest continent and is also an island continent.
Australia and Antarctica are the island continents, however, Europe is smaller than Antarctica.
