This is what we found on Wikipedia regarding the Batushka:

Batushka (Cyrillic spelling: 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.

In 2018 Bartłomiej Krysiuk (also known as Bartek Krysiuk), owner of independent label Witching Hour and at the time lead singer of the band, tried to remove Drabikowski from the band and without his consent, attempted to register a trademark for the name 'Batushka'. Krysiuk along with members of the live backing band were signed to Metal Blade Records under that name. Subsequently, Drabikowski filed a lawsuit against him.

In 2019, Krysiuk announced that his version of Batushka would carry on without Drabikowski and it would consist of a lineup featuring long-staying touring musicians who had performed with the band during the first album tours. This group released its own recordings and began performing separately from Drabikowski, which caused confusion among fans who were unaware of the split and the existence of two bands using the Batushka name. Drabikowski protested the move claiming Krysiuk's band was not legitimate as Krysiuk maintained that Drabikowski did not own the rights over the name and concept of the band.

In 2020, Krysiuk shared court documents which stated that he 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.
