Adolf II of Holstein (c. 1128 – 6 July 1164) was the Count of Schauenburg and Holstein from 1130 until his death, though he was briefly out of Holstein from 1137 until 1142. He succeeded his father Adolf I under the regency of his mother, Hildewa.
After the death of the Emperor Lothair II (1137), the new king, Conrad III, granted the Duchy of Saxony to Albert the Bear. Adolf was consequently deprived of Holstein because he was a Welf supporter and refused to recognise Albert as duke. He only received it back in 1142 when Conrad and Henry the Lion were reconciled.
In 1143, Henry and Adolf divided the rule of the conquered Slavic lands to their east. Adolf received Wagria with its chief city, the castle of Sigberg, built by Lothair, and Henry received Polabia with Ratzeburg as its capital. Sigberg became Adolf's chief fortress and most regular seat. Adolf promoted Christianity in his new lands, especially through the missionary work of Vicelinus. Adolf, encouraged by Lothair, promoted German colonisation of his Slavic territories, especially with colonists from not only his own lands but also from Westphalia, Flanders, Holland, Utrecht, and Frisia.
In 1143 or 1144, Adolf built Lübeck, the first German port on the Baltic Sea. Adolf also built the first castle (1143) in Lübeck: a wood and earth construction. In 1157, Lübeck was burned and rebuilt by Henry the Lion, to whom Adolf transferred it in 1159.
