fortified centres were then built by the energies of the village communities; and, once they had built their walls, once a common interest had been created in this new sanctuary--the town walls--they soon understood that they could henceforward resist the encroachments of the inner enemies, the lords, as well as the invasions of foreigners. A new life of freedom began to develop within the fortified enclosures. The medieval city was born.(14) No period of history could better illustrate the constructive powers of the popular masses than the tenth and eleventh centuries, when the fortified villages and market-places, representing so many "oases amidst the feudal forest," began to free themselves from their lord's yoke, and slowly elaborated the future city organization; but, unhappily, this is a period about which historical information is especially scarce: we know the results, but little has reached us about the means by which they were achieved. Under the protection of their walls the cities' folkmotes--either quite independent, or led by the chief noble or merchant families--conquered and maintained the right of electing the military defensor and supreme judge of the town, or at least of choosing between those who pretended to occupy this position. In Italy the young communes were continually sending away their defensors or domini, fighting those who refused to go. The same went on in the East. In Bohemia, rich and poor alike (Bohemicae gentis magni et parvi, nobiles et ignobiles) took part in the election;(15) while, the vyeches (folkmotes) of the Russian cities regularly elected their dukes--always from the same Rurik family--covenanted with them, and sent the knyaz away if he had provoked discontent.(16) At the same time in most cities of Western and Southern Europe, the tendency was to take for defensor a bishop whom the city had elected itself; and so many bishops took the lead in protecting the "immunities" of the towns and in defending their liberties, that numbers of them were considered, after their death, as saints and special patrons of different cities. St. Uthelred of Winchester, St. Ulrik of Augsburg, St. Wolfgang of Ratisbon, St. Heribert of Cologne, St. Adalbert of Prague, and so on, as well as many abbots and monks, became so many cities' saints for having acted in defence of popular rights.(17) And under the new defensors, whether laic or clerical, the citizens conquered full self-jurisdiction and self-administration for their folkmotes.(18)
