Provence. During his early years of reign, Hugh somewhat improved the central administration of the kingdom, achieving rather more (though not total) success against the Magyar raids that had been plaguing Italy for several decades. In September 928, Hugh met with Rudolph of France and Herbert II of Vermandois in Burgundy. Hugh granted Herbert's son Odo Vienne in opposition to Charles Constantine. He was still in conflict with Rudolph of Burgundy and hoped to ally with the King of France against the Burgundian monarch. By 930, however, Charles was in complete control of Vienne and by 931, Rudolph of France was claiming suzerainty over the Viennois and Lyonnais. In light of these reverses in his transalpine policy, Hugh turned his attention towards securing his rule in Italy and receiving the imperial crown. He induced the Italian nobility to recognise his son Lothair as their next king and crowned him in April 931. That same year, he accused his half-brother Lambert of Tuscany of conspiring for the crown – perhaps with the support of a faction of nobles – and deposed him, bestowing the March of Tuscany on his brother Boso. Hugh, however, had other reasons for deposing Lambert, who presented an obstacle to his second marriage to Marozia. Lambert's supporters called in Rudolph of Burgundy, whom Hugh bribed off with the gift of the Viennois and Lyonnais, which Rudolph successfully occupied. In 933, Rudolph relinquished all his rights to Italy. In 936, Hugh replaced Boso of Tuscany with his own son Humbert. He granted Octavion in the Viennois to Hugh Taillefer and patched up his relations with Charles Constantine in a final effort to save influence in Provence. Second marriage However, Hugh's attempt to strengthen his power further by a second marriage failed disastrously. His bride was Marozia, senatrix and effective ruler of Rome and widow first of Alberic I of Spoleto and then of Hugh's own half-brother Guy of Tuscany. This last fact, though, meant that the marriage was illegal under canon law, because of the relationship of affinity between them – a matter that Hugh tried to circumvent by disowning and eliminating the descendants of his mother's second marriage and giving Tuscany to a relative on his father's side of the family, Boso. This in turn, however, alarmed Alberic II, Marozia's teenage son or stepson from her first marriage, who, appealing to Roman distrust of the foreign troops
