GNOME began partly because KDE depended on Qt, whose license the Free Software Foundation (FSF) considered nonfree from 1996 to 1998. People building systems committed to free software could not use that library, so they could not include KDE. GNOME emerged in 1997 as a free-software desktop alternative. The dispute helps explain why both projects exist, but it was not a literal war or the only reason people and Linux distributions chose different desktops.
What was the licensing dispute?
KDE was announced in 1996 as a graphical desktop for Unix systems, built with the Qt toolkit and C++. The FSF’s account describes Qt’s license during 1996–1998 as nonfree. Because a desktop built with Qt depended on that library, systems that required free software could not use KDE without accepting a licensing restriction they rejected. The FSF explains this history in its account of the GNU Project; KDE’s own retrospective also discusses the early dispute in its history of KDE.
That distinction matters: the concern was Qt’s licensing and what it meant for systems committed to free software, not simply that KDE itself was proprietary. “Licensing war” is a colorful shorthand for a licensing dispute and the community response to it.
How did GNOME emerge?
In 1997, Miguel de Icaza and Federico Mena founded GNOME. The project’s history says it chose GTK+ under the GNU Lesser General Public License (LGPL) as the basis for a free-software desktop. That made GNOME an alternative for people who wanted a desktop that did not depend on Qt under the license then at issue. GNOME’s project history describes that choice, and its about page identifies the founders.
#1 Best Overall
So the short answer to “Was GNOME created because KDE used Qt?” is: partly. The Qt licensing concern was a key motivation for creating a free-software alternative, but the available histories do not establish it as the sole reason GNOME or KDE continued to develop as separate projects.

Why are both desktops still associated with Linux?
Linux is the kernel, not a single complete desktop system. GNU/Linux distributions can package different desktop environments, and GNOME and KDE developed as separate projects with different toolkit foundations. The early licensing dispute explains one important reason GNOME was started; it does not mean the dispute remains unchanged today or that licensing alone accounts for current desktop choices.
The Qt licensing change and the KDE Free Qt Foundation addressed the central historical concern. KDE’s account says the original arguments became obsolete after Qt was relicensed under the GPL. The historical split therefore helps explain the projects’ origins, rather than establishing that current KDE is nonfree.

What this history does—and does not—explain
- It explains: why a free-software desktop alternative to Qt-based KDE was seen as necessary in the late 1990s.
- It does not establish: that licensing was the only reason users or distributions chose one desktop over another.
- It does not compare: present-day usability, performance, accessibility, features, or distribution defaults; those require separate, current evidence.
