In 1994 the district was created, when the previous districts Hainichen, Rochlitz and part the district Chemnitz were merged. In August 2008, as a part of the district reform in Saxony, the districts of Döbeln, Freiberg and Mittweida were merged into the new district Mittelsachsen.
The district was located in the foothills of the Ore Mountains, only the area in the northwest around Rochlitz belongs to the Leipzig Bay. In this area is also the lowest elevation with 144 m above sea level; the highest elevation is in Hausdorf (part of Frankenberg) with 488 m. The three main rivers in the district are the Zwickauer Mulde, Chemnitz and Zschopau.
