have also been found, and the unhealthy Czech habit of eating too much pork roast, not to speak of dumplings and kraut, may be a very old tradition). In the seventh and eighth centuries, the Slavs (who had risen against the Avars in the east and the Franks in the west) began to build their own fortifications, large burgs protected by wood and stone constructions to house the emerging families of the noble warriors and to protect ancient trade routes and access to the river fords. There were, possibly, five of these burgs in the Prague region, the most important being, once again, close to the Šárka cliffs, at Butovice and, later, at Levý Hradec, north of present-day Prague. In these burgs, archaeologists have found evidence of fine artistry and Frankish coins, suggesting the growing importance of long-distance commerce.
Archaeological discoveries about the ninth and the tenth centuries firmly combine with evidence in written documents, including Frankish annals, Bavarian topographies, Arabic and Hebrew texts, to fix the places and shapes of events, however distant and diffuse. In the ninth century at least a dozen Slavic tribes were settled in diverse regions of Bohemia, in some contrast to more centralized Moravia, and new groups of feudal chieftains and their retinues emerged to make decisions about war and peace and their peoples. Each tribe began to build fortified burgs and communities, and a contemporary Bavarian geographer indicated that the “Beheimare” (whoever that was) had fifteen civitates and those of the more powerful “Fraganeo” region forty (he may have overstated the numbers).
It was at Levý Hradec that the family of the Pemyslids began to consolidate its power over the Czechs and pushed its claims from there. Only the Slavníkovci, a clan who later united the tribes east and south of Prague and ruled two-fifths of Bohemia, came to resist the Prague dukes, occasionally allying themselves with Saxons and Poles to do so. But on September 28, 995, their well-built civitas Libice fell, and the Slavníkovci and their people, men, women, and children, were mercilessly slaughtered by the Pemyslids, who consolidated their power in the eleventh and twelfth centuries and ruled until 1306.
As happened recurrently in later Czech history, the Pfemyslids and other dukes of the Bohemian tribes confronted neighboring realms of greater power and, throughout the melodramatic ninth century, had a difficult time in furthering their interests by military force or, if necessary, by carefully shifting allegiances. Francis Dvorník (born 1893), the grand old man of early Slavic history, deplores that, in matters spiritual, these western Slavs (including those in Bohemia) were faced early with the only recently Christianized young and half-barbarian Carolingian empire, rather than being able to live, as did the southern Slavs, closer to the gates of Byzantium, long Christian and heir to Greek culture. The “Behaimi” were, after protracted resistance to the Carolingian empire, forced to accept its hegemony (806), symbolized by a yearly tribute of five hundred measures of silver and one hundred and twenty oxen (used by Nazi historiography more than a thousand years later as a political argument about the German power in Bohemia); Bohemian representatives appeared at imperial gatherings carrying the appropriate gifts; and on January 13, 845, fourteen Bohemian duces (chieftains) appeared in Regensburg, capital of East Franconia and starting point of the missionary expeditions to the east, to be Christianized together with their retinues. Not much later, a Frankish expansion eastward ran against the resistance of the rulers of Great Moravia, which originally united Moravia with central parts of Slovakia, and Frankish armies again and again marched through or close to Bohemian territory to reestablish “law and order.”
By the year 862, Prince Rostislav of Great Moravia (after the pope had ignored his wishes) asked the
