Festive and ceremonial culture of Ukrainians at the beginning of the 21st century develops under the influence of pan-European trends. The dynamic cultural integration processes condition the sphere of spiritual life with various innovative and borrowed phenomena. Ukrainians actively adapt the components inherent in representatives of different nationalities in modern family rituals, add new practices to the mandatory “checklist” of sanctioned ritual actions, shorten or change traditional components taking into account the aesthetic and symbolic requests of the future spouse. At the beginning of the aggressor’s full-scale invasion of the territory of Ukraine, a reduction or refusal to perform a number of complex ritual actions is observed among the population in connection with the prevention of risks associated with the danger of shelling. At the same time, we note that consolidation processes are gaining momentum among Ukrainians, accompanied by the self-presentation of ethnicity and the demonstration of the characteristics of traditional culture as defining differences of a separate national community in opposition to the hostile belief about “national unity”. The focusing on the preservation of ethnoculture, as a state-building factor, stimulated Ukrainians to renew festive and ceremonial life activities with an emphasis on the performance and observance of traditional rituals. In particular, the practice of traditional components in the festive and ritual sphere is in the trend of Ukrainian humanity today; there is a trend of re-actualization of traditional rites and customs; entire scenarios for conducting and celebrating family events are being developed, which involve the consistent reproduction of traditional actions and rituals in all their regional or narrow-local diversity. The existence of the main traditional components of the festive and ceremonial culture of Ukrainians during the martial law ensures their preservation for the future as one of the defining and original features of the Ukrainian people.
