One peasant revolt scared Japan into sealing its borders for over 200 years
Starting in 1637, tens of thousands of overtaxed peasants and persecuted Christians in the Shimabara region rose up against the Japanese shogunate, holding out in a fortress siege through the winter before being crushed, with nearly all rebels killed. Alarmed that foreign missionaries and trade had helped fuel the revolt, the shogunate banned Christianity outright and sealed Japan off from almost all outside contact, a near-total isolation that lasted over two centuries.
