Kościuszko had been venerated as a saint during communism in Poland (first Polish Division formed in Sovitet Union was named after him, my school was named after him and many others). But today is omitted from history and forgotten.
The problem with Kosciuszko (and some other Polish officers of the era like Jakub Jasiński) is that they were deadly serious with abolishing slavery in America and serfdom in Poland (basically the same institution), giving full citizenship rights to all human beeings and liquidating privileged landowning class (szlachta - nobility).
This did not sit well with people who hijacked narrative of Polish history - descendants of landowning class bancrupted by Industrial Revolution in second half of XIX century. They romanticesed good old days of szlachta and have always perceived Kosciuszko as troblesome figure and rabble rouser.
This is absolutely false. I'm a student in Poland so I'm fresh on this and - politics aside - he is a very big figure in Polish history books, and everybody knows about him.
(The Kościuszko Insurrection is one of the more important dates, that each student is supposed to remember)
