| Dirty summary (not involving AI): Just like Christianity arrived in Poland by marriage of Mieszko with Czech princess Doubravka/Dobrawa in 10th century, we also adapted Czech alphabet (and thus Latin) from Jan Hus efforts of codifying Czech language. Scholars believe that around same time Polish began to develop as a separate language. And up until the 13th century it was still possible to communicate with southern neighbors without much of issues. Between 15th and 16th century Polish orthography forms; Stanisław Zaborowski and Jan Kochanowski tried to customize alphabet by introducing letters that would accurately reflected Polish phonology at that time - their alphabets proposals were really long. Jumping to the Partitions period, where heavy russification aims at eradicating the Polish language and culture. There were attempts of introducing Cyrillic script but occupier's efforts eventually failed - Polish people stood up; literature of these times was full of titles exploring patriotism, love for homeland as a theme. Linguistic reform of 1936 molds language to what we know today. The communistic period introduced second person plural within the public language, which naturally exists today in Czech and Slovak (vykání). Here it didn't lasted as it was unnatural and politically branded. While Polish language divides into dialects, that time also forms the standard Polish dialect, as post-WW2 migrations blurred the differences. Today our language is heavily populated with borrowed words and terms from English, which in some case become "naturalized" - hater become hejter. |

Poland on the other hand has Catholicism as a key identity marker, although IME living in Poland for a decade, this is fading rapidly with younger people.
