Ferdinand I, Holy Roman Emperor, is represented in this anonymous portrait as a young archduke in his native Spain. He left Spain in his early twenties, to start his life as future King of the Romans and successor to his grandfather, Maximilian I. His older brother Charles eventually succeeded as Holy Roman Emperor, but Ferdinand was elected after Charles's abdication. Philip, Charles's son, inherited Spain and became King Philip II of Spain. Ferdinand ruled between 1558 and 1564, for nearly six years.Artist: Unknown
