The Linux Kongress was an annual conference of Linux developers from around the world, that took place every year from 1994 to 2010. It started as a two-day conference in 1994, when Linux was in the early stages of development, and by 2003 had become a four-day event. It occurred every year in Germany except 2001 and 2007. During its lifespan, Linux-Kongress was one of the three major international grass-roots Linux and Open Source conferences in the world, along with linux.conf.au and Ottawa Linux Symposium.
The focus of Linux-Kongress was development topics, either in kernel or user space. The conference language was English. By the end, the event consisted of two days of conference preceded by two days of tutorials.
