History
In 1897 an unofficial German National Outdoor Championships (German players only) were established. In 1902 following the creation the German Lawn Tennis Association they became official. Following World War II when Germany was divided into East and West this tournament was then re branded as the West German National Outdoor Championships for West Germany and the East German National Outdoor Championships for East Germany.

In 1961 the West German National Indoor Championships were established. The first championships were played in Dortmund, and the first winners of the singles events were Peter Scholl (men's), and Edda Buding (women's). The championships were not held in 1964 and 1968. In 1990 following the reunification of Germany both the east and west events were merged into a single German Closed Indoor Championships, with the same for the outdoor championships. In 1980 two editions of tournament was held this year the first in January, and the second in December due to the German Tennis Federation moving the event till the latter date and continued to stage them at the end of the year. In 1996 six years after unification both the German Closed Outdoor Championships and German Closed Indoor Championships ended and were merged into a single German National Championships to be played either indoors or outdoors.
