The study of Mohammad and Masoud Ghaznavid's political regime in literary-historical works based on Likert's hypothesis (997-1041)

Iranian political regimes during Islamic period were the reproduction of the political regimes before Islam. Ghaznavid was the only Turkish government that unlike many Iranian governments، the way they seized power was not on tribal basis. Ghaznavid rulers were not the head of any tribes but warriors who could gain different military categories putting their efforts and had the nature of militarism and authoritarianism in them. The present article seeks to investigate the two levels (structural and environmental) of Ghaznavid government، based on Likert`s Hypothesis and according to the prominent literary-historical works of the period، Beihaghi history and poetical works of three courtier poets Onsori، Farrokhi، and Manuchehri. On the Linkert`s structural level the way ruling system cooporates، concentrates and does not concentrate، and on the environmental level، the value system and the quality of its effect on Ghaznavids` leadership method are specified. Ghaznavid gave holiness to their government justified their crimes by promoting the divine value system and assigning their sovereignty to the Prophet (PBUH) through the ruler of Baghdad. This way، they created a dictatorial regime which was highly focused; that is، the rulers were the only figures who could decide. Thus، the first system proposed by Linkert، authoritarian style، ruled there.
