Task: Question Understanding
Input (English): Passage: The Long Turkish War or Thirteen Years' War was an indecisive land war between the Habsburg Monarchy and the Ottoman Empire, primarily over the Principalities of Wallachia, Transylvania and Moldavia. It was waged from 1593 to 1606 but in Europe it is sometimes called the Fifteen Years War, reckoning from the 1591-92 Turkish campaign that captured Bihać. In the series of Ottoman wars in Europe it was the major test of force between the Ottoman-Venetian War  and the Cretan War . The next of the major Ottoman-Habsburg wars was the Great Turkish War of 1683-99. Overall, the conflict consisted in a great number of costly battles and sieges, but with very little result for either side.
