Tenpo

Tenpō (天保^?) was a Japanese era name (年号, nengō^?, "year name") after Bunsei and before Kōka. The period spanned from December 1830 through December 1844. The reigning emperor was Ninko-tennō (仁孝天皇^?).

The Tenpō era is often described as the beginning of the end of bafuku government. Though the era accomplished much through its reforms, and also culturally speaking, the injury inflicted on the Tokugawa system of government during the Tenpō period was unparalleled. Public order and dissatisfaction with government was a main issue, but the bafuku was not entirely at fault for the stir amongst the people. For example, the failure of crops in 1833, which soon became a lengthy disaster endured for over four years called the Great Tenpō famine, was caused mainly due to poor weather conditions. Because crops could not grow under these circumstances, prices began to skyrocket. These dire circumstances sparked many rebellions and riots across Japan over the course of the Tenpō years. Weary and desperate for someone to blame, the people rose up against the government, and Ōshio Heihachirō, known for leading one of the largest rebellions, made a statement to implicate "the natural disasters as sure signs of Heavens's discontent with the government".Mizuno Tadakuni's reforms were meant to remedy these economic issues, but the reforms could not rescue the bakufu from its ultimate collapse.
