This book explores the rabbinic debates surrounding the creation of such enclosures in North American cities and examines the evolution of American Orthodox communities from the late nineteenth century through the 1960s.

By the mid-twentieth century, these rabbinic disputes reveal an established, religiously observant community forming its own traditions.
