Norway was the first.

Thank you. Can I get to know all the countries that got to the center of the South Pole (,and put their flags there)?

"The flags of the original signatories to the Antarctic Treaty (who had territorial claims over, or national or scientific interest in the Antarctic) are flown at (or rather near, since the Pole moves) the South Pole. They are: Argentina, Australia, Belgium, Chile, France, Japan, New Zealand, Norway, South Africa, the United Kingdom and the United States, USSR was a signatory, so the flag of the Russian Federation is now flown."

The country that arrived at the South Pole, the center of Antarctica, is credited to Norway. The first successful expedition to the South Pole was led by Roald Amundsen, a Norwegian explorer, in December 1911. To determine the answer to this question, you can follow these steps:

1. Start by understanding that the South Pole is located in Antarctica, a continent at the southernmost part of the Earth.
2. Recognize that the race to the South Pole in the early 20th century involved several expeditions by various nations, including Norway, the United Kingdom, and others.
3. Research and compare the accomplishments of different explorers and expeditions related to the South Pole. This could include reading books, articles, or online resources about Antarctic exploration.
4. Specifically, look for information about Roald Amundsen, as he is widely recognized as the first person to successfully reach the South Pole.
5. The research will reveal that Roald Amundsen, leading a Norwegian expedition, reached the South Pole on December 14, 1911, beating his British rival, Robert Falcon Scott.
6. By compiling this information, you will find that the country credited with arriving at the South Pole is Norway, under the leadership of Roald Amundsen.
