AbstractSystemic vasculitis is a manifold group of systemic autoimmune diseases characterized by the inflammation of the blood vessels. The first clinical cases of systemic vasculitis were described in the Middle Ages, and most of the currently recognised nosological forms were reported in the first half of the 20th century. The first attempt to create a united classification of vasculitis was performed by P. Zeek in 1952. In the following decades accumulation of the data on the etiology and pathogenesis of different vasculitis guided researchers from different countries in their attempts to improve classification. The main principles of classification were the size of the affected blood vessels, disease etiology and pathogenesis. In 1990 American College of Rheumatology (ACR) published classification criteria for seven forms of the systemic vasculitis, that gave a significant contribution to the conduction of large-scale studies in this field. However, the first international nomenclature of vasculitis was developed only in 1994 during the Consensus Conference in Chapel Hill. Revised and augmented version of this nomenclature was created in 2012 and is still valid. An important step in the development of the classification of vasculitis was a joint project of ACR and EULAR aimed to develop new diagnostic and classification criteria for vasculitis (DCVAS). The first result of this project are the new classification criteria for granulomatosis with polyangiitis, microscopic polyangiitis and eosinophilic granulomatosis with polyangiitis published in 2022. In general, the evolution of the classification of vasculitis occurs under the influence of the progress in the understanding of their etiology and pathogenesis.
