Outline of Final Research Achievements

In this study, the historical character of local influential figures(Dogo) during the Sengoku period was analysed in the fields of Oyamato-Gou, Isshi-gun, Ise Province and Kuchino-Gou, Sunto-gun, Suruga Province. As a result, the following findings were obtained.
(1) The local authorities(Dogo) in the Oyamato-Gou were autonomous small lords who developed their own private territorial control. They realised a legal order for resolving territorial disputes between native landowners(Dogo) in a judgmental and consensual manner, in which the characteristics of Ikki-like regional power are strongly expressed.
(2) The Uematsu clan, a native of Kuchino Gou in the pre-mid-Sengoku period, was a self-reliant entity that ruled its own territory and people, and this character was not breached by the Kunishu power (the Kazurayama clan). However, they later lost their autonomy under the influence of the Sengoku daimyo power (the Hojo clan).

Academic Significance and Societal Importance of the Research Achievements

これまでの戦国期研究において、戦国大名ら地域権力の支配体制（大名による領国の一元支配）や、その下での在地社会のあり方（村請制を介した、大名による村落団体の統治・管轄）は、しばしば近世社会の性格を先取りするものとされてきた。他方、本研究は、それとは異なる側面、すなわち、後の近世社会では主流となり得なかった、戦国期固有の地域秩序を明らかにするものとなった。土豪層による共和的な地域統治である一揆体制、および国衆支配下における土豪層の存在形態（自律的な領主制）の具体的解明がそれに当たるが、これらの成果は、当該期の地域社会の中で育まれた、いわば「未発の契機」に光を当てる点で、一定の意義をもつであろう。
