Development of the district The area fell to
Prussia in 1815, which in 1816 created the three districts Heinsberg,
Erkelenz and
Geilenkirchen. In 1932 the districts Heinsberg and Geilenkirchen were merged, and in 1972 Erkelenz district was merged as well. In 1975 the district reached its present size when the municipality
Niederkrüchten was moved to the district
Viersen.
Prominent role in the Covid-19 pandemic The district became a center of the
COVID-19 pandemic in Germany. The
Robert Koch Institute listed Heinsberg as an especially affected area (). Since the first cases were discovered in this area, the district was around two weeks "ahead" of the rest of
Germany. A research group of the
University of Bonn started to use the affected area as a testing site to study the
novel coronavirus and to search for ways to handle the situation in the best possible way. ==Coat of arms==
