This is what we found on Wikipedia regarding the Batushka:

Batushka (stylized in Cyrillic as БАТЮШКА) is a Polish black metal band based in Białystok, founded by Krzysztof Drabikowski in 2015. Their music and lyrics, which are written exclusively in Church Slavonic language, are inspired by the Eastern Orthodox Church. The band members wear religious habits and Eastern Orthodox schemas during live performances to conceal their identities. In contrast with many other black metal bands, they use eight-string guitars.

A dispute between Drabikowski and Bart Krysiuk began when Bartłomiej Krysiuk signed the band to Metal Blade Records in 2017. Subsequently, Krysiuk registered the trademark to 'Batushka'. Drabikowski was in strong protest of these actions, and the relationship between the two members escalated from bad to worse. At this time, Drabikowski was not involving the band members with his new material. Krysiuk, along with members of the band, recorded an album to fulfill the obligation with Metal Blade. This was done without regard for Drabikowski, who did not want to release a new album at this time. Drabikowski responded by filing a lawsuit against Krysiuk.

In 2019, Krysiuk announced that Batushka activities would carry on without Drabikowski. The band would consist of a lineup featuring long-staying touring musicians who had performed with the band during the Litourgiya tours. This group released its own recordings and began performing separately from Drabikowski, causing confusion among fans who were unaware of the split and the existence of two bands using the Batushka name. Drabikowski protested the move and does not consider Krysiuk's band legitimate while Krysiuk claimed Drabikowski does not own the rights over the name and concept of the band. In 2020, Krysiuk shared court documents which stated that Krysiuk had legal rights to perform and release music under the name 'Batushka'. In 2024, the Polish courts ruled in favor of Drabikowski in a first instance ruling, while Krysiuk promised to appeal the ruling.

On 9 September 2024, Krysiuk announced that his band will no longer be called "Batushka" and will adopt the name "Patriarkh".
