The idea of ​​the royal crown of the rulers of Poland in thirteenth-century political thought, historiography and historiosophy was a phenomenon in many respects exceptional. It drew from many sources. It brought with it a response to the current needs of the Piast princes who had supra-regional ambitions. It was above all an expression of the intellectual maturity of the Kraków, Greater Poland and Silesian church elites. At the same time, it testified to the political maturity of people from the circle of power and the broadly understood powerful knighthood from various parts of Poland. It responded to the political and historiosophical ideas of a similar nature that appeared in Europe at that time. It brought with it a new stage in the history of Polish medieval historiography, the direct consequence of which was the historiography of the reborn Kingdom of of Poland in the fourteenth century.
