Because the definition of a mountain is not universally agreed upon, a distinction is made between main summits and other peaks.
In the Alps a summit is classed as independent, according to the UIAA definition, if it has a prominence of 30 metres (98 ft) or more.
Likewise fully on German territory, but considerably less independent, are the Middle Höllentalspitze (2,742 m) and the Hochblassen (2,703 m).
A majority of the summits were verifiably climbed in the 19th century; the Watzmann and Hoher Göll for example as early as 1800.
For example, during the time of the Holy Roman Empire up to 1806, the Ortler in present-day South Tyrol, at 3,905 m (12,812 ft), was the highest German mountain.
During the Nazi era from 1938 to 1945 this title went to the Großglockner which, at 3,797 m (12,457 ft), is today the highest mountain in Austria.
