The epic “Koroglu” (“Köroğlu”, “Koroghlu”, “Korogli”, “Kerogli”), despite its late origin (XVII century), in comparison with other Turkic epics, has no analogue in its prevalence. The formation of the epic started from the XVII century and lasted until the XIX century. Later, it was subjected to various artistic developments and changes, becoming a unique example of overcoming linguistic and ethnic boundaries . Mainly handed down by narrators, it began to be written down in the first half of XIX century to the beginning of XX century, and the stories spread in Central Asia, especially in 1930–1940s and later.

Field ethnographic materials, collected in the regions of Lori, Tavush, Syunik and Lori in 2009–2023, indicate that the use of berries in the Armenian nutrition system has changed. Unlike the traditional system in which they were used as components of dishes, already in the middle of the 20th century, as a result of the availability of sugar and introduction of new technologies, berries became ingredients mainly for making candies.
