Modern Western translation of documents related to Bushidō began in the 1970s with Carl Steenstrup, who performed research into the ethical codes of famous Samurai clans including Hōjō Sōun and Imagawa Sadayo [REF].
In May 2008, Thomas Cleary translated a collection of 22 writings on Bushido by warriors, scholars, political advisers, and educators, spanning 500 years from the 14th to the 19th centuries.
