For centuries Maciejowice was part of the Land of Stezyca, which belonged to Lesser Poland’s Sandomierz Voivodeship. In 1794, the Battle of Maciejowice took place near the village. In the early years of the Polish statehood, this part of the country was sparsely populated, due to proximity of the eastern border. First local village, mentioned in documents, is Kochow (one kilometer south of Maciejowice), which was founded in 1155. In the late 12th century, a Roman Catholic parish of Kochow was established, and in the 15th century, the area of the future Maciejowice was purchased by a local nobleman Kacper Maciejowski. The village remained in the hands of the Maciejowski family until the late 17th century.
