In 1697, during the Great Turkish War, a raid was led by Prince Eugene of Savoy of the Habsburg Monarchy against the Ottoman Empire, which conquered Sarajevo and left it plague-infected and burned to the ground. After his men had looted thoroughly, they set the city on fire and destroyed nearly all of it in one day. Only a handful of neighborhoods, some mosques, and an Orthodox church, were left standing. Numerous other fires weakened the city, which was later rebuilt but never fully recovered from the destruction. By 1807, it had only some 60,000 residents.
