The SANFL came into being in as we know it in 1907 known as the SAFL.
I believe that it was previously know as SAFA having its origins going back to 1877 but not 100% sure on that part
The league suspended play at the end of 1915 due to WW. While most clubs did enter a competition designed to raise funds for the war effort it was not recognised by the SAFL and as such did not recognise games played or premierships as not all clubs competed during its 3 years of existence 1916-1918
Below is the minor round and major round records of the 7 teams playing in the comp at the time.
