In short: The Feast of the Intercession, or Pokrov, commemorates a miraculous vision of the Virgin Mary shielding the faithful with her cloak in Constantinople. While rooted in Byzantine tradition, this celebration evolved into a profound cultural touchstone in Slavic nations, eventually shaping military identity and modern public holidays in Ukraine.

The feast originates from a 10th-century account in Constantinople. According to tradition, St. Andrew the Blessed Fool-for-Christ witnessed the Virgin Mary appearing in the Blachernae church. Surrounded by angels, she prayed for the world before spreading her veil over the congregation as a symbol of divine protection. This event is celebrated annually on October 1 in the Eastern Orthodox and Byzantine Catholic traditions.

While the vision occurred in Byzantium, the feast gained unique fervor in Russia, Belarus, and Ukraine. Veneration of the Pokrov dates back to the 12th century in these regions. In Ukraine, the holiday became deeply intertwined with the history of the Zaporozhian Cossacks, who viewed the Theotokos as their heavenly patroness. This connection was formalized in the 18th-century Pylyp Orlyk Constitution, which designated Pokrova as one of three major annual conventions for the Cossack council.

The significance of the feast has persisted into the modern era, shifting from purely religious observance to national commemoration. In 1999, Ukraine officially recognized the day as Ukrainian Cossack Day. By 2014, a presidential decree promoted the date to Defenders of Ukraine Day, cementing the link between the ancient protective imagery of the Virgin Mary and the contemporary defense of the nation. The feast is also physically memorialized in iconic architecture, such as Saint Basil's Cathedral in Moscow and the 15th-century fortress-church in Sutkivtsi, Ukraine.

Iconography of the feast typically depicts the Virgin Mary holding a veil, often surrounded by saints and angels. While distinct from the Western Virgin of Mercy image, some iconographic versions share similarities in how the cloak is portrayed. Despite its deep roots in East Slavic culture, the feast is not observed by Oriental Orthodox Churches, highlighting its specific development within the Byzantine Rite and its subsequent cultural adaptation in Slavic lands.
