A deed from 1130 mentions Berthold von Pagin,
ministerialis of
Lothair III, emperor of the
Holy Roman Empire, who gave his name to the town in the form of Peine. The Peine Castle, which no longer exists, dated to this era or before. The 1201
Hildesheim Chronicle describes a
feud between the bishop Hartbert von
Hildesheim and the brothers Ekbert and Gunzelin von
Wolfenbüttel. Earl Gunzelin von Wolfenbüttel was the commander-in-chief of the German army and
seneschal in attendance of
Otto IV, emperor of the Holy Roman Empire. Gunzelin prevailed and won control of Burg Peine and the surrounding area. South of the castle, Gunzelin founded the town of Peine in 1218 or 1220. In 1223, the settlement gained
town privileges. Gunzelin's
coat of arms has been the town's symbol ever since. In 1256, Peine was conquered by Duke Albrecht of
Braunschweig-Lüneburg, and after Gunzelin's death in 1260, his sons
(see: House of Asseburg) lost the
fief of Peine to the bishop of Hildesheim. Otto I of Braunschweig-Lüneburg, bishop of Hildesheim, 1260–1279, gave Earl Wedekind von Poppenburg the castle, town and county of Peine as a fief. Otto later incorporated Peine as a
market town. Also in 1260, Peine earned the right to mint and issue coins and was, with a few interruptions, a
mint for the Bishopric of Hildesheim until 1428. After the imminent shelling of Peine by American tank troops shortly before the end of
World War II, the cultural
functionary and teacher
Hans Michael Finger, mayor Wiard Bronleewe and others from the Peine command post went to surrender to the American commander Captain Daniel A. Grundmann in Rosenthal on the morning of April 10, 1945. Finger was acting as an interpreter. Thanks to Finger's explanations, the further bombardment of Peine was averted almost at the last minute. In 1954 and 1956, two of the largest German medieval treasures of silver (95 pieces of round
bullion, weighing 7.5 kg, dating from the 14th century) were found under the streets
Stederdorfer Straße and
Horstweg. The Peine city archive was directed by
Michael Utecht from 1988 to 2019. ==Subdivisions==
