Masovian Voivodeship or Mazovia Province [4] (Polish : województwo mazowieckie [vɔjɛˈvut͡stfɔ mazɔˈvʲɛtskʲɛ] ) is the largest and most populous of the 16 Polish provinces, or voivodeships. It occupies 35,579 square kilometres (13,737 sq mi) of east-central Poland, and has 5,411,446 inhabitants. [1] Its principal cities are Warsaw (1.783 million) in the centre of the Warsaw metropolitan area, Radom (212,230) in the south, Płock (119,709) in the west, Siedlce (77,990) in the east, and Ostrołęka (52,071) in the north. The capital of the voivodeship is the national capital, Warsaw.


The province was created on January 1, 1999, out of the former Warsaw, Płock, Ciechanów, Ostrołęka, Siedlce and Radom Voivodeships, pursuant to the Polish local government reforms adopted in 1998. The province's name recalls the traditional name of the region, Mazovia, with which it is roughly coterminous. However, southern part of the voivodeship, with Radom, historically belongs to Lesser Poland, while Łomża and its surroundings, even though historically part of Mazovia, now is part of Podlaskie Voivodeship.

It is bordered by six other voivodeships: Warmian-Masurian to the north, Podlaskie to the north-east, Lublin to the south-east, Świętokrzyskie to the south, Łódź to the south-west, and Kuyavian-Pomeranian to the north-west.

Mazovia is the centre of science, research, education, industry and infrastructure in the country. [5] It currently has the lowest unemployment rate in Poland and is classified as a very high income province. [5] Moreover, it is popular among holidaymakers due to the number of historical monuments and greenery; forests cover over 20% of the voivodeship's area, where pines and oaks predominate in the regional landscape. [6] Additionally, the Kampinos National Park located within Masovia is a UNESCO-designated biosphere reserve.

Masovian Voivodeship (1526–1795)

Masovia Voivodeship, 1526–1795 (Polish : Województwo Mazowieckie) was an administrative region of the Kingdom of Poland, and of the Polish–Lithuanian Commonwealth, from the 15th century until the partitions of the Polish-Lithuanian Commonwealth (1795). Together with Płock and Rawa Voivodeships, it formed the province (prowincja) of Masovia.

Masovian Voivodeship (1816–1837)

Masovian Voivodeship was one of the voivodeships of Congress Poland. It was formed from Warsaw Department, and transformed into Masovia Governorate.


Koleje Mazowieckie (Masovian Railways) 316B-002 (6), Zmigrod, 2015-12-05.jpg
Koleje Mazowieckie (Masovian Railways)

There are three main road routes that pass through the voivodeship: Cork–Berlin–Poznań–Warszawa–Minsk–Moscow–Omsk, Prague–Wrocław–Warsaw–Białystok–Helsinki and Pskov–Gdańsk–Warsaw–Kraków–Budapest.

Currently, there are various stretches of autostrada in the area, with the A2 autostrada connecting the region, and therefore the capital city, with the rest of Europe. The autostrada passes directly through the voivodship from west to east, connecting it with Belarus and Germany. However, the A2 is yet to be built east of Warsaw to connect Poland with Belarus. The S8 expressway connects Warsaw with Białystok in the neighboring eastern province, along with the S17 being built to connect Warsaw with Lublin.

The railroad system is based on Koleje Mazowieckie and PKP Intercity.

The main international airport in the region is Warsaw Frederic Chopin Airport.


Masovian Voivodeship is the wealthiest province in Poland. The gross domestic product (GDP) of the province was €112.2 billion in 2018, accounting for 22.6% of the Polish economic output. GDP per capita adjusted for purchasing power was €34,400 or 114% of the EU27 average in the same year. [14]


The unemployment rate stood at 4.8% in 2017 and was higher than the national and the European average. [15]

Congress Poland was subdivided several times from its creation in 1815 until its dissolution in 1918.

In 1816 the administrative divisions were changed to forms that were more traditionally Polish: voivodeships, obwóds and powiats. Following the November Uprising, the subdivisions were again changed in 1837 to bring the subdivisions closer to the structure of the Russian Empire when guberniyas (governorates) were introduced. In this way, Congress Poland was gradually transformed into the "Vistulan Country". Over the next several decades, various smaller reforms were carried out, either changing the smaller administrative units or merging/splitting various guberniyas.
