Masovian Voivodship

The Masovian Voivodship (in Polish województwo mazowieckie) is the largest and most populous of the sixteen Polish administrative regions or voivodships created in 1999. It covers an area of 35,598 km² in eastern-central Poland and contains nearly 5.1 million inhabitants. Its principal cities are Warsaw (population 1.6 million) in the centre, Radom (230,000) in the south, Plock (130,000) in the west, Siedlce (75,000) in the east, and Ostroleka (55,000) in the north.

It was created on 1 January 1999 out of the former Warsaw, Plock, Ciechanow, Ostroleka, Siedlce and Radom voivodships as a result of Local Goverment Reorganization Act of 1998. The voivodship's name recalls the region's traditional name of Mazovia (Mazowsze) with which it more or less corresponds.
