The Cyrillization of Polish has been practised in many forms and began in the mid-19th century in the Russian Empire. Between 1772 and 1815, the Russian Empire seized about four-fifths of Poland-Lithuania, where Polish was the leading official language. Polish remained the official language of the incorporated Polish-Lithuanian territories until the late 1830s. Later, it was fully replaced with Russian in the mid-1860s. A middle stage for the transition was the use of the Russian-style Cyrillic for writing Polish.[1]

Example of text:[3]
The system of the Cyrillization of Polish proper names, as employed in today's Russia, emerged during the 1970s in the post-war Soviet Union. It is a form of orthographic transcription.[4]
Another form of Russian-based polish cyrilic has been in use since the early 1990s, in Polish-language religious books produced for Catholics in western Belarus (i.e. Grodno Diocese).[5]

The Lord's prayer (Grodno variant):
Ukrainian cyrillic is mostly the same as Russian, except that и and ы are represented by і and и respectively. є is only used for je.
The Lord's prayer:
I and Y are both represented by И. L and ł are both represented by Л. Ó, despite being pronounced as U, is represented by О. Ś and Ź are mostly represented by С and З, although Ш and Ж are rarely used.
