History
Between 1987 and 1993 significant delays occurred in bringing out a new version of GNU Emacs. In the late 1980s, Richard P. Gabriel's Lucid Inc. faced a requirement to ship Emacs to support the Energize C++ IDE. So Lucid recruited a team to improve and extend the code, with the intention that their new version, released in 1991, would form the basis of GNU Emacs version 19. However, they did not have time to wait for their changes to be accepted by the Free Software Foundation (FSF). Lucid continued developing and maintaining their version of Emacs, while the FSF released version 19 of GNU Emacs a year later, while merging some of the code and adapting some other parts.
When Lucid went out of business in 1994, other developers picked up the code. Companies such as Sun Microsystems wanted to carry on shipping Lucid Emacs, however, using the trademark had become legally ambiguous because no one knew who would eventually control the trademark "Lucid". Accordingly the "X" in XEmacs represents a compromise among the parties involved in developing XEmacs.
The "X" in XEmacs is thus not related to the X Window System. XEmacs has always supported text-based terminals and windowing systems other than X11. Installers can compile both XEmacs and GNU Emacs with and without X support. For a period of time XEmacs even had some terminal-specific features, such as coloring, that GNU Emacs lacked.
The software community generally refers to GNU Emacs, XEmacs (and a number of other similar editors) collectively or individually as emacsen (by analogy with boxen) or as emacs, since they both take their inspiration from the original TECO Emacs.

Famous quotes containing the word history:
“Regarding History as the slaughter-bench at which the happiness of peoples, the wisdom of States, and the virtue of individuals have been victimized—the question involuntarily arises—to what principle, to what final aim these enormous sacrifices have been offered.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
“Don’t give your opinions about Art and the Purpose of Life. They are of little interest and, anyway, you can’t express them. Don’t analyse yourself. Give the relevant facts and let your readers make their own judgments. Stick to your story. It is not the most important subject in history but it is one about which you are uniquely qualified to speak.”
—Evelyn Waugh (1903–1966)
“Psychology keeps trying to vindicate human nature. History keeps undermining the effort.”
—Mason Cooley (b. 1927)
