History.
The area now comprising Minamishimabara was under the control of the Arima clan, who ruled from Hinoe Castle in the Muromachi period. The area was the site of considerable foreign trade and Portuguese and Spanish missionary activity, and by the early Edo period, a large percentage of the population were "Kirishitan". After the start of the national isolation policy, the Tokugawa Bakufu banned Christianity from 1614 and replaced Arima Naozumi with Matsukura Shigemasa, who relocated the capital of Shimabara Domain to Shimabara Castle is what is now Shimabara. Due to misgovernment, high taxes and persecution of Christianity, the population rose in the Shimabara Rebellion of 1637, with the peasants occupying the fortress of Hara Castle as their strongpoint. The rebellion was suppressed with extreme severity by the Tokugawa Bakufu, and the area of Minamishimabara was ruled by a branch of the Matsudaira clan from 1668 to 1774 and from 1774 to 1871.
