The town is situated in the Masovian Voivodeship (since 1999), previously it was part of the Ciechanów Voivodeship (since 1975). During the Invasion of Poland in 1939, the Battle of Mława was fought to the north of the city.
The first mention of Mława comes from July 2, 1426, when three princes of Mazovia - Siemowit V, Trojden II and Władysław I came here to a session of a local court. It is not known if Mława had already been an urban center, as there are no sources which would prove it. Three years later, Mława was incorporated as a town and in 1521 during the Polish-Teutonic War, the town was captured and looted by the Teutonic Knights. In 1659 the town was burned by the Swedish troops, and in 1795, following the Partitions of Poland, Mława became part of the Kingdom of Prussia.
After Napoleonic Wars, in the 1815 Congress of Vienna Mława (along with the entire province) was incorporated into the Russian Partition of Poland where it remained until World War I. Since the town was located along the pre-1914 imperial Russian-German border, Mława was a place of heavy fighting between the two opposing armies. During the interbellum, the town was assigned to the Warsaw Voivodeship (1919–39). The government of the Second Polish Republic constructed several fortifications there due to proximity of the German border.
World War II
In the opening stages of World War II, the advancing German army faced strong resistance from the Polish Army in the Battle of Mława otherwise known as the Defence of the Mława between September 1 and September 3, 1939. During the occupation of Poland by Nazi Germany in World War II the town (known as Mielau in German) gave its name to the Truppenübungsplatz "Mielau" military training range built by prisoners of the Soldau concentration camp nearby and nicknamed the New Berlin. The facility was used by the Nazis for repairing and refitting army tanks in Operation Barbarossa, and for testing anti-tank weapons and artillery on an area of 300 square kilometres (120 sq mi). Some fifteen villages around Krzywonoś were completely dismantled to make room for it and 25,000 people were expelled in the area. Similar Nazi German military ranges in occupied Poland included the SS TruppenÜbungsPlatz Heidelager located in Pustków, Podkarpackie Voivodeship and the SS-Truppenübungsplatz Westpreußen located in Dziemiany.
Prior to the arrival of the Soviets in 1945, Mława was the location of the German massacre of 364 prisoners of the forced labour camp adjacent to the Truppenübungsplatz "Mielau".
There's a large LG factory manufacturing TV sets and monitors located in the city. Mława was the first site of deployment for CONVAERO Polska's Bio-Dry™ technology project, where an annual throughput of 96,000 tonnes of MSW shredded is processed to achieve a 25% reduction in moisture and results in an easily separated and recycled end material
