Mazovia
The borders of contemporary Mazovian Voivodeship ( province ) , which was created in 1999 , do not exactly reflect the original size of Mazovia , as they do not include the historically Mazovian cities of Łomża and Łowicz , but include the historically Lesser Polish cities of Radom and Siedlce .
