Annigeri is a town near Hubli in Dharwad District of Karnataka. Recently  the archeology department has found 601 human skulls in an excavation.  The skulls date back to 10th to 12th century. According to reliable  sources, Archeology Department has found very important materials and  references mentioned in the Bombay State Dharwad Gazetteer about a  massacre that took place near Annigeri.
J M Nagaiah, associate professor of Dr RC Hiremath Institute of Kannada  Studies ( KUD), has said that he has discovered the inscriptions, one  each at Hottur near Shiggon taluk of old Dharwad district, and at  Gawarwad near Annigeri.
According to the Hottur inscription, Chola emperor Rajaraja, during an  expedition, had attacked Belaval-300 province with the help of his  nine-lakh-strong army and captured Annigeri during 1007-08. The emperor  then tried to forcibly convert people into Shaivas (followers of Lord  Shiva). He is also said to have ruthlessly chopped people, including  children, who refused to be Shaivas. King Sataysharava Irive Bemdag of  Chalukyas of Kalyan was ruling Annigeri then.
