In the [[Early Middle Ages]], the territory was inhabited by the [[Masovians]], an old [[Polish tribes|Polish tribe]]. It formed part of Poland since its establishment in the 10th century, with the then-regional capital [[Płock]] being the capital of Poland from 1079 to 1138. The ''Wzgórze Tumskie'' ("Cathedral Hill") in Płock with the [[Płock Castle]] and the [[Płock Cathedral|Catholic Cathedral]], seat of one of the oldest Polish dioceses, est. in 1075, which contains the sarcophagi of a number of [[Polish monarchs]], is listed as a [[Historic Monument (Poland)|Historic Monument of Poland]].<ref>{{Cite Polish law|title=Rozporządzenie Prezydenta Rzeczypospolitej Polskiej z dnia 20 kwietnia 2018 r. w sprawie uznania za pomnik historii "Płock - Wzgórze Tumskie"|year=2018|number=1003}}</ref> Later, Płock, Warsaw and [[Czersk, Masovian Voivodeship|Czersk]] were medieval ducal seats of the [[Piast dynasty]]. 

In 1505, Radom hosted the session of the [[Sejm of the Kingdom of Poland|Sejm]] (Polish Parliament), which enacted the ''[[Nihil novi]]'' act, and in the 16th century, Warsaw hosted several sessions of the Sejm,<ref>{{cite book|last=Konopczyński|first=Władysław|year=1948|title=Chronologia sejmów polskich 1493–1793|language=pl|location=Kraków|publisher=[[Polish Academy of Arts and Sciences|Polska Akademia Umiejętności]]|pages=133, 136, 139–140}}</ref> before King [[Sigismund III Vasa]] moved the Polish capital from [[Kraków]] to Warsaw in 1596. 

Following the late-18th-century [[Partitions of Poland]], the region witnessed several uprisings against foreign rule: the [[Kościuszko Uprising]] of 1794, the [[November Uprising]] of 1830–1831, and the [[January Uprising]] of 1863–1864. 

In the [[interbellum]], the region was part of reborn independent Poland. In 1920, the region was [[Polish–Soviet War|invaded by Soviet Russia]], but Poland secured its freedom in the victorious [[Battle of Warsaw (1920)|Battle of Warsaw]]. The southern part of the current province was rapidly industrialized as part of the [[Central Industrial Region (Poland)|Central Industrial Region]] of Poland.
