The two decades encompassing the Civil War and Reconstruction (1860–80) saw the establishment of many Jewish congregations and the development of Reform Judaism in the United States. The period also saw the climax of the so-called “German period” of American Jewry. This, and the fact that prominent Reformers like David Einhorn and Samuel Hirsch were Germans to the core, suggest a connection between nascent American Reform Judaism and its German counterpart. It is too simplistic, though, to see American Reform as a mere transplant of German Reform. Using Jewish congregations of the period in Georgia and North and South Carolina as examples of the Reform process in regions of the United States distinct from major metropolitan areas like New York, Philadelphia, Baltimore, and Cincinnati, this essay analyzes German aspects of American Reform Judaism, focusing on the demographic composition of communities (i.e., the entirety of Jewish residents in one town), membership of congregations (i.e., organized religious bodies), religious concepts, and rabbis of German origin. The essay argues that in these southern states, the need to adapt to American realities and the urge and pressure to Americanize were more crucial for the process than were German influences. In this region the Reform movement, while possibly inspired by German ideas, was an American development that arose from American needs and convictions.
