The High Middle Ages in Europe were marked by progressive changes in warfare. Old weapons are being improved but also accompanied by the appearance of new and deadlier forms of weapons. Advanced blacksmithing techniques and improved armor gradually altered the form of swords and also impacted the invention of more lengthy knives, daggers and various hybrid weapons. Categorization of swords used in this thesis is based on the works of E. Oakeshott and A. Geibig, and also complemented with derivatives of contemporary authors. By analyzing the archeological findings, we can see that High Middle Ages swords had continuously gained more length and built a stronger form in order to pierce a chain mail with greater success. The ending of High Middle Ages was marked by development of massive types of swords intended for slashing, and gracile types for piercing attacks. Also, the blade and the hilt of sword had gotten bigger, and the most famous type of medieval swords – hand and a half sword - was created.In the Late Middle Ages, many types of swords had been specialized for inflicting stabs only. However, stabbing was quickly replaced by older and newer types of swords that combine slashing and stabbing. In Croatia, southeastern Europe and most parts of southern Europe a new type of convex cross section blade was used that evolved from older types. Meanwhile, in other parts of Europe, a diamond shaped cross section blades were favored. Both of the stated blades (convex and diamond) represent a basis that created the great sword from which early modern two handed swords were made. This complex progress is also noted in development of short knives that were intended for stabbing and for slashing and stabbing/slashing combined. Early medieval Seax influenced creation of stabbing knives that were used until the end of Late Middle Ages, after which daggers and Kords (i.e. Bauernwehr; Hauswehr) were used. Every kind of short weapon had gotten its enlarged form and type through the Late Middle Age. The first form of a hybrid European saber – later type of falchion – was a combination of Early medieval substratum (war cleaver and falchion) and Eastern influence (Avarian, Hungarian, Tatarian saber). Yet, the first true European saber was a Kord type four (4) that progressed after the Turkish expansion and the occurrence of Turkish saber on southeastern European territory. While Croatian area lacks in daggers and falchion artefacts, it reveals a high number of artifacts and findings on Kords and swords that tell us a story of great warfare culture based on hundreds of years of battles.
