The Kamakura shogunate (1192-1333), Japan's first samurai regime, is sometimes depicted as the beginning of a long slide in women's rights. Although being a women, Hōjō Masako (1157-1225) was instrumental in the development of many of the shogunate's institutions. Masako revolved disagreements, regulated the regency, and mobilized troops as the wife of the first shogun and mother of the subsequent two. This strong woman was credited with being a shogun in her own right, which is recorded in contemporary sources. Later versions, however, paint Masako as a clever, cruel lady who explore and analyze literature, the major role Hōjō Masako played in the Shogunate and how she contributed to the society of the Kamakura period.
