What religious conflict is portrayed in Silence?

In the film Silence, directed by Martin Scorsese, the religious conflict centers on the intense persecution of Roman Catholic missionaries and their Japanese converts in 17th-century Japan.12

During this era, the Tokugawa shogunate viewed foreign missionaries and the growing Kirishitan movement as a threat to political stability. The government enforced a strict proscription of the faith, requiring individuals to renounce Christianity—often by stepping on a fumi-e, an image of Christ or the Virgin Mary—under the threat of torture or death. The film explores the profound moral and spiritual struggles of Jesuit priests who face these brutal conditions while attempting to maintain their faith and support the underground Christian community.321
