In Lithuania, we also had some sad episodes for this instrument. The Czar regime in the 19th century banned organs at Unitarian churches in Lithuania which were converted to Orthodoxy.
The soviet times were bad for us of course (including for organs). The only good thing perhaps is that in those days the historical organs were largely untouched and many of them are still in more or less historical condition. However, this also means that the majority is also in an urgent need of quality restoration.
By the way, if you would like to know more about the history of organ building in Lithuania, here is my English translation of the overview Rimantas Gučas did for his book "Lietuvos vargonai" (Lithuanian Organs).
