The primary reason why the shogun decided to establish a rule was to maintain political control over Japan. From the late 12th to the mid-19th century, Japan was ruled by a series of hereditary military dictators known as shoguns. The shogun held the real power in Japan, while the emperor, whose position was largely symbolic, held a ceremonial role.
To unify the country under a centralised authority
Japan had been experiencing internal conflicts and power struggles among various clans and warlords for centuries before the shogunate's establishment. The shogun sought to unify the country under a centralised authority, bringing an end to the constant strife and establishing peace and stability in the nation.
To protect Japan from external threats
Japan was also vulnerable to external threats from its neighbours, primarily from China and Korea. By establishing a strong and centralised government, the shogun aimed to strengthen the country's defence and protect its sovereignty from foreign invasions and influence.
To regulate trade and economy
The shogunate also played a significant role in regulating trade and economy. The shoguns established trade policies and regulations to control the flow of goods, prices, and taxation, ensuring that the economy operated smoothly and efficiently.
To preserve Japanese traditions and culture
The shogun was deeply rooted in Japanese culture and traditions. They made efforts to preserve and promote traditional values, customs, and arts while resisting the influence of foreign cultures and religions, especially Christianity, which was seen as a potential threat to the shogun's authority and the unity of the nation.
In summary, the shogun established a rule to maintain political control, unify the country, protect Japan from external threats, regulate trade and economy, and preserve Japanese traditions and culture.
