Deutschland Tour
Already in 1911, a "national" cycling race of over 1,500 km was held in the German Empire (Germany was then lots of more or less independent kingdoms, duchies, and other little countries ). Until 1931 several Tours were held, organised by different groups. In 1931 the first Deutschlandtour was held.  The race was well organised and exciting between 1937 and 1939, but stopped again at the start of World War II.
