Abstract:The Britain branch of the Rothschild, as the Jewish financial magnate second to none in the 19th century, finished the aristocratic process and entered the upper-class society. This not only helped the family to gain a good public image and establish social network connections, but also contributed in converting the professional role of the family. Thus, the family got new social breakthroughs constantly. The aristocratic process of the Rothschild's family also exerted profound influence on the whole England society.
