In the years 1419-1436, in the territory of the then Czech Kingdom, but also in the borderlands of Germany, wars were fought between the supporters of Jan Hus, i.e. the Hussites, and the rulers of the Luxembourg dynasty seeking to impose their power on them. These wars, as you can easily guess, went down in history under the name of the Hussite Wars. In their course, the Hussites often achieved great victories thanks to the use of several novelties. First of all, they used still primitive firearms on a relatively large scale (for example, the so-called crossbones), but also during the battle they assumed a defensive position, using special cars, which they connected with chains to form a rolling stock. From these cars they fought against the advancing enemy troops. The main strength of the Hussite armies was infantry, cavalry was used in counterattacks, most often in the last stage of the battle. The Hussites were also lucky with outstanding commanders, such as Jan Żiżka and Prokop the Great. The Hussites also won many victories in the field - mainly at Witkowa Góra (1420) or at Domażlice (1431).
