text: Construction of castles in this period was often connected to the necessity to establish a strong central power against local fragmentation, or in newly conquered lands: examples are the large buildings programs of Edward I of England in Wales, Philip I August of France, the Ezzelino IV da Romano and the Scaligers in northern Italy, Frederick II and Charles I of Anjou in southern Italy (often reusing former Norman or even Byzantine and Lombard structures), King Denis I in Portugal, and notably the Teutonic Knights in their conquest of Pagan lands in Prussia and Poland.
