Just at this time, however, the state of affairs changed, for Tuscany was beginning to feel the influence of Frederic I. (Barbarossa). This emperor, finding that Duke Guelfo was unable to make himself respected, despatched (1162-3) the Archbishop Reinhold of Cologne, a man of energy and brains, with the title of "Italiae archicancellarius et imperatoriae maiestatis legatus," and charged to reorganise the Imperial administration on a new plan. Frederic regarded the dissolution of the margraviate as an accomplished fact, and wished to assume the direct government of its various component parts by means of German counts or Podestà, in the manner already adopted by him in Lombardy. Reinhold set to the task with zeal, establishing German governors and garrisons in the principal castles of the _contado_; and where no castles remained new ones were erected.[154] San Miniato, with its tower on the hill, dominating the suburb of San Genesio below, was the headquarters of this new administration. Here Reinhold established Eberhard von Amern with the title of "_Comes et Federici imperatoris legatus_."[155] Frederic's scheme of policy was clear and precise; but in order to carry it into effect against the will of communes that were already emancipated, and against the interests of many native counts, would have required much time and a great army, both of which were lacking at the moment. Reinhold was soon called elsewhere for other undertakings, and although his successor, the Archbishop Christian of Mayence, was likewise a man of ability, their efforts led to few practical results. Their only success consisted in the amount of money squeezed from the people; for, as a chronicler puts it, "like good fishermen, they drew everything cleverly into their nets." But they established no firm political basis.
