Ming dynasty
The Hongwu Emperor had many sons and made them the leaders of the 13 different parts of China. He did not stay in Khanbaliq. He made his old base Yingtian (today's Nanjing) into the new capital city. He wanted China to be more traditional and more Chinese, so he ended most government support for other religions and made Christianity against the law. He wanted China to take care of itself, so he ended most buying and selling of things from other countries. He made a list of rules for his family, and they mostly followed them during the rest of the Ming.
