This period also saw the emergence of Albanian literature, written by Christians such as Pjetër Bogdani. Some of these Christian Albanian thinkers, like Bogdani himself, ultimately advocated for an Albania outside of Ottoman control, and at the end of the 17th century, Bogdani and his colleague Raspasani, raised an army of thousands of Kosovar Albanians in support of the Austrians in the Great Turkish War. However, when this effort failed to expel Ottoman rule from the area yet again, many of Kosovo's Catholics fled to Hungary.
