The Tumulus culture (German:Hügelgräberkultur) was the dominant material culture in Central Europe during the Middle Bronze Age ( 1600 to 1300 BC).
It was the descendant of the Unetice culture. Its heartland was the area previously occupied by the Unetice culture, and its territory included parts of Germany, the Czech Republic, Austria, Switzerland, the Carpathian Basin, Poland and France. It was succeeded by the Late Bronze Age Urnfield culture.
The Tumulus culture is distinguished by the practice of burying the dead beneath burial mounds (tumuli or kurgans).
In 1902, Paul Reinecke distinguished a number of cultural horizons based on research of Bronze Age hoards and tumuli in periods covered by these cultural horizons are shown in the table below (right). The Tumulus culture was prevalent during the Bronze Age periods B, C1, and C2. Tumuli have been used elsewhere in Europe from the Stone Age to the Iron Age; the term "Tumulus culture" specifically refers to the South German variant of the Bronze Age. In the table, Ha designates Hallstatt. Archaeological horizons Hallstatt A–B are part of the Bronze Age Urnfield culture, while horizons Hallstatt C–D are the type site for the Iron Age Hallstatt culture.
The Tumulus culture was eminently a warrior society, which expanded with new chiefdoms eastward into the Carpathian Basin (up to the river Tisza), and northward into Polish and Central European Únětice territories. The culture's dispersed settlements consisted of villages or homesteads centred on fortified structures such as hillforts. Significant fortified settlements include the Heuneburg, Bullenheimer Berg, Ehrenbürg, and Bernstorf. Fortification walls were built from wood, stone and clay. The massive 3.6m-wide wall surrounding the plateau of the Ehrenbürg resembled later murus gallicus fortifications known from the Iron Age. 'Cyclopean' stone fortifications topped with wooden battlements were constructed 1400 BC at the large hillfort of Stätteberg in Bavaria.
