Hidden Rock is one of the more powerful ninja villages in the world, allowing its leader to be called a "Kage." As such it is one of the Five Great Shinobi Countries. Approximately 13 years before the start of the series, the village was at war with Leaf. Their invasion path took them through the Grass Country. The efforts of the man who became Fourth Hokage and his team consisting of Hatake Kakashi, Uchiha Obito and Rin helped turned back their assault.

The village has prospered since, and now is the starter of the greatest war in the history of the shinobi wars.
