Timeline

  1. 1121–1125Goslar · Lower SaxonyIn 1106 Lothair succeeded as Duke of Saxony (after the death of Magnus, last duke of the Billung dynasty), and from Henry V's later years he confronted both the emperor and Hohenstaufen forces. Together with princes such as Henry IX of the Welf family, he gradually expanded the Saxon–Welf alliance in the 1120s, preparing for the struggle for the throne after Henry V's childless death.
  2. 1125–1128Mainz · Rhineland-PalatinateAfter Henry V died at Utrecht in May 1125, the princes elected Lothair king at Mainz, defeating the Hohenstaufen candidates Frederick II of Swabia and Conrad of Franconia. After his coronation at Aachen he set about restoring imperial authority and relied on his Welf allies to consolidate the south.
  3. 1128–1130Regensburg · BavariaBetween 1127 and 1129 Lothair's relations with Henry X, Duke of Bavaria (Henry the Proud), deteriorated, and conflict erupted over territories and inheritance rights. By around 1130 Lothair had gradually suppressed Hohenstaufen resistance in Swabia and Franconia and was preparing his later expedition south to Italy to seek papal coronation as emperor.
