History

Emacs was originally developed in 1976 by Richard Stallman, the founder of the Free Software Foundation. It was initially based on the editor TECO and was intended to be a standalone text editor. Over the years, Emacs has undergone continuous development, with numerous contributors adding new features and improvements.

In 1985, Emacs was split into two main branches: GNU Emacs and XEmacs. GNU Emacs is the most popular version today, and it is actively maintained by the GNU Project. Emacs has seen continuous updates and enhancements over the years, with the latest major Release being Emacs 28.1 in 2023.

Emacs’s longevity and enduring popularity are a testament to its power, flexibility, and active community of users and developers. It remains a cornerstone of the open-source software ecosystem and continues to be a valuable tool for countless users worldwide.
