2199

2199 is a science fiction novel written by American author Isaac Asimov. It was first published in 1963 and is the third book in Asimov's Foundation series. The story is set in the distant future, approximately 7,500 years after the events of the first two books in the series, Foundation and Foundation and Empire.

The novel follows the efforts of the Foundation, a group of scientists and scholars who have fled to the outer rim of the galaxy to preserve human knowledge and culture. The Foundation is led by Hari Seldon, a mathematician who has developed a science called psychohistory, which allows him to predict the future of humanity.

The story begins with the Foundation's efforts to establish a new society on the planet Terminus. However, they face numerous challenges, including political intrigue, religious fanaticism, and the threat of the Mule, a powerful and ruthless leader who seeks to destroy the Foundation.

As the story progresses, the Foundation's leaders must make difficult decisions about the future of humanity, including whether to embrace or reject the Mule's offer of help. Ultimately, the Foundation succeeds in establishing a new society, but at a great cost.

2199 is notable for its exploration of themes such as the preservation of knowledge, the role of science in society, and the challenges of establishing a new civilization. It is also notable for its use of psychohistory, a concept that has become a staple of science fiction and has been referenced in numerous other works.
