The village of Broitzem was first mentioned in documents during the 12th century. Originally mostly a farming village, Broitzem became connected to the railway network via the Hildesheim–Brunswick railway during the 19th century and people increasingly started to commute into work in the city. By the early 20th century, the village had about 1000 inhabitants. During the 20th century, new residential and commercial areas were developed in Broitzem, causing a growth of population. In 1974, the village, until then part of the disbanded rural district of Braunschweig, was incorporated into the city of Braunschweig and became a city district.
