Which 1637–1638 uprising in Kyushu was led by the teenage Christian leader Amakusa Shirō?

The 1637–1638 Shimabara Rebellion in Kyushu was led by the teenage Christian leader Amakusa Shirō.

The uprising began in the Shimabara Peninsula and the Amakusa Islands, areas suffering from heavy taxation, famine, and harsh treatment of Christians. Many rebels were peasants, while others were former samurai. They rallied around Amakusa Shirō, a young Christian figure regarded by supporters as possessing special religious significance.

The rebels fortified themselves at Hara Castle, where they resisted forces sent by the Tokugawa shogunate. The government eventually assembled a much larger army and received limited naval assistance from the Dutch, who fired on the castle. Hara Castle fell in April 1638, and most defenders were killed.

The rebellion intensified the Tokugawa government’s suppression of Christianity and contributed to stricter controls on foreign contact. It also led officials to scrutinize local administration, because excessive taxation and abuse had helped provoke the revolt. Despite its religious dimension, the rebellion was driven by several overlapping social, economic, and political causes.
