The times of the Second Polish Republic were a particularly important period in the development of Polish archeology, because after Poland regained independence, the first state institution was established to organize the protection of archaeological monuments throughout the country. It was the State Group of Prehistoric Monuments Conservators functioning in the years 1920–1928. Their activities in the Kielce voivodeship brought particularly interesting results. Conservators and delegates of the State Group of Prehistoric Monuments Conservators did a lot in the field of inventory and protection of archaeological monuments in the Kielce region, undertaking surface and excavation rescue research, as well as popularizing archeology among the inhabitants of the region. The result of their activities was the registration, discovery, and exploration of many archaeological sites, including such valuable ones as a complex of multicultural sites in Złota near Sandomierz and in Książnice Wielkie, and a unique complex of striped flint mines in Krzemionki near Ostrowiec. The sites discovered at that time in the Kielce voivodeship are still the subject of interest and research to Polish archaeologists.
