Village in History
The village of Kumogakure seemed to have been at war with Konohagakure, but signed a peace treaty with the Leaf Village to end the war. However, the peace agreement was broken when a Lightning shinobi named Gashira attempted to kidnap Hinata Hyuga, but was killed in the process by her father Hiashi Hyuga. Many believe that the deed was done so that the Byakugan could be researched, but the Lightning ninjas denied all claims, but demands a shinobi with the Byakugan as payment for the death of one of their shinobi. Originally this was supposed to be Hinata's father, Hiashi, but Neji's father, Hizashi offered himself. This event is what triggered Neji's hatred towards the Main Branch of the Hyuga clan. He didn't know that his father offered himself before, but found this out when he lost at the Chuunin exams.
