In 1971 Imre Boba published a monograph, Moravia's History Reconsidered, in which he argued that the ninth-century Slavic principality of Moravia was located not in central Czechoslovakia, as modern scholars have assumed, but in northern Yugoslavia, in the vicinity of the Roman provincial capital of Sirmium . In his book and in subsequent articles, Boba has assembled an impressive array of sources — Latin, Byzantine Greek, Slavic, Old English, and others — to support his hypothesis. Based on this evidence, the (...) arguments Boba makes are plausible, and one would expect scholars to take them seriously. (shrink)
