The South German League was a political entity that existed from 2038 to 2044. It consisted of the former German federal states of Bavaria and Baden-Württemberg.
These traditionally very conservative states openly opposed the acceptance of metahumans and the influx of Eurowars refugees. When their opinions went unheard on the federal level they declared their independence from the Federal Republic of Germany.
Attempts to incorporate Switzerland and Austria were rejected by the respective governments.
The SGL's end came when proposed laws for tightened economic government control angered the SGL's corporate backers.
