When the Kamakura bakufu (Japanese feudal government headed by a shogun) came to power toward the end of the 12th century, some myoshu farmers, especially those in eastern regions, gained positions in the shogunate government and became gokenin (an immediate vassal of the shogunate in the Kamakura and Muromachi through Edo periods) or were appointed as jito (local landlord).
