Correct Option: 4
Explanation:
The Minamoto and the Taira clans
The Minamoto (or Minamoto-Shi or Genji) or Taira (or Hei-Shi or Heike) warrior clans were rivals for imperial power over Japan, and in the conflict drew many other clans variously to their side. The Minamoto forces won, and established the Kamakura shogunate, a military dictatorship that dominated Japan from 1192 to 1333. According to Wikipedia "The end of the Genpei War and beginning of the Kamakura shogunate marked the rise to power of the warrior class (samurai) and the gradual suppression of the power of the emperor, who was compelled to govern without effective political or military power, being effectively reduced to a purely symbolical and ceremonial head of state, until the Meiji Restoration over 650 years later."
