Kamakura is known among Buddhists for having been the cradle of Nichiren Buddhism during the 13th century. Founder Nichiren wasn't a native; he was born in Awa Province, in today's Chiba Prefecture. But it was only natural for a preacher to come here because the city was the political centre of the country at the time. Nichiren settled down in a straw hut in the Matsubagayatsu (literally "pine needle valley") district, where three temples (Ankokuron-ji, Myōhō–ji, and Chōshō-ji), have been fighting for centuries for the honour of being the true heir of the master. During his turbulent life Nichiren came and went, but Kamakura always remained at the heart of his religious activities. It's here that, when he was about to be executed by the Hōjō Regent for being a troublemaker, he was allegedly saved by a miracle; it's in Kamakura that he wrote his famous , or "Treatise on Peace and Righteousness"; it's here that legend says he was rescued and fed by monkeys and it's here that he preached.
