985 at Frankfort, Henry was re-established in Bavaria and his cousin was forced to content himself with Carinthia and the March of Verona, now again formed into a separate duchy. At first Theophano and Adelaide acted as joint regents, but the influence of the former soon became predominant. In the administration of the kingdom she was assisted by Willigis, Archbishop of Mayence, who took charge of affairs in Germany during her absence in Italy in 989. The minority fell at a critical time. The death of King Lothair of France in 986, followed a year later by the death of his son, Louis V, without an heir, plunged France into a civil war, during which the opposing parties of Hugh Capet and Charles of Lower Lorraine, the representative of the Carolingian house, each sought to win the help of the regents of Germany. Theophano succeeded in maintaining a neutral attitude; but the dynastic question was no sooner settled in favour of Hugh, than another hot dispute broke out as the result of the decision of the synod held at the monastery of St Basle de Verzy near Rheims (June 991). The Archbishop Arnulf of Rheims, the natural son of Lothair, was deposed from his see and Gerbert was appointed in his place. Germany was again called upon to play a part in the affairs of France. A synod of German bishops held at Ingelheim in 994 declared against the decisions of St Basle. The controversy dragged on until 998, when Otto solved the problem by making Gerbert Archbishop of Ravenna, thus leaving Rheims in undisputed possession of Arnulf.
Still more serious was the general state of unrest on the Eastern frontier. During the years 985-987 there was continual fighting against the Wends and Bohemians. With the help of Mesco, Duke of the Poles, Meissen was recovered for the Margrave Eckhard. When in 990 a war broke out between the Poles and Bohemians Theophano supported Mesco while Boleslav was allied with the Lusatians. The Bohemians, fearing to engage with the Germans, treated for peace. The Saxons acted as mediators but barely escaped destruction through the treachery of the barbarians. It was Boleslav, and not their ally Mesco, who enabled the Saxon army to escape in safety to Magdeburg. On 15 June 991 Theophano died. Adelaide, who now returned from Italy and undertook the regency, had neither the energy nor the statesmanlike qualities of the younger Empress, and the weakness of her rule soon became apparent in the frontier warfare. Brandenburg in 991 became the centre of operations. The young king captured it with the help of Mesco, but no sooner was his back turned than it was reconquered for the Lusatians by a Saxon named Kiso. Otto renewed the attack in the following year with the help of Henry of Bavaria and Boleslav of Bohemia; Boleslav, who had succeeded his father Mesco as prince of the Poles, being threatened with a war with the Russians, was unable to accompany the king in person but sent troops to his assistance. But not till the spring of 993 was the fortress recovered, and then not by the
