This proceeded apace with the change to autocratic rule at the hands of the central Hojo family (Tokuso, the patrimonial head of the main branch of the Hojo clan), namely the establishment of the Tokuso autocracy; the Hojo clan's Shugo provinces were 2 in the early Kamakura period around 1200 (36 to other clans, 4 with no Shugo), around 1250 they were 17 (24 to other clans, 5 with no Shugo), around 1285 they were 33 (18 to other clans, 5 with no Shugo), and in 1333 at the end of the Kamakura period they were 38 (15 to other clans, 5 with no Shugo), expanding rapidly from around the middle Kamakura period.
これは、北条時頼の頃から北条本家（得宗）による政治の専制化、すなわち得宗専制が確立していったことに伴うもので、北条一門の守護国は、鎌倉初期の1200年頃に2国（他氏36国、守護不設置4国）、1250年頃に17国（他氏24国、不設置5国）、1285年頃に33国（他氏18国、不設置5国）、鎌倉最末期の1333年には38国（他氏15国、不設置5国）と鎌倉中期を境に一気に増加していた。
