The concept of s.c unification tendencies, actively sought by scholars as early as the first half of the 13th century, has become a historiographical paradigm in Polish studies. These tendencies are believed to have intensified over time, culminating in the early 14th century with the monarchy of the last Piast rulers of Kuyavia. This process is presented as unidirectional and driven by objective historical forces. The first stage of this supposed progression is linked to the so-called monarchy of the Silesian dukes and their alleged coronation plans, as well as the development of a mature "ideology of unification" by the Dominican chronicler Vincent. This ideology is thought to have influenced Piast rulers in shaping their political programs. In this framework, unification and the royal crown are treated as synonymous, despite the first Piast coronation in the 13th century clearly contradicting this view. This paper aims to critically reassess these entrenched interpretations.
