The first explorer to reach the South Pole was Roald Amundsen, a Norwegian polar explorer. He successfully arrived at the pole on December 14, 1911, leading a team of five men and utilizing specially designed sledges and dogs for the expedition. Amundsen’s achievement beat his British rival, Robert Falcon Scott, who reached the pole a month later. This expedition was significant not only for its historical achievement but also for the scientific discoveries made during the journey. Amundsen's careful preparation and understanding of the harsh polar environment were crucial to his success.
