Atahualpa (c. 1502 – 1533) was the last effective Inca Emperor, reigning from April 1532 until his capture and execution in July 1533. He is known for his role in the Inca Civil War and his interactions with the Spanish conquistadors. Atahualpa was the son of Emperor Huayna Capac. After his father's death, Atahualpa was appointed governor of Quito. A civil war erupted between Atahualpa and his half-brother Huáscar over the Incan throne. Atahualpa eventually defeated and captured Huáscar, becoming the sole ruler of the Inca Empire.
In November 1532, Francisco Pizarro and his Spanish forces arrived in Cajamarca and captured Atahualpa. Despite Atahualpa offering a substantial ransom of gold and silver for his release, the Spanish accused him of treason and conspiracy. He was sentenced to death and executed by strangulation in July 1533. His death marked the end of the Inca Empire as an independent state. Atahualpa's story has become a symbol of indigenous resistance and the tragedy of conquest, inspiring various artistic and literary works. Recent expeditions have been launched to find the lost gold treasure of Atahualpa in the Llanganates Mountains in Ecuador.
