Several important cultural achievements were made in the decade. Roger Bacon published important scientific work named "Opus Majus." Also, Thomas Aquinas published "Summa contra Gentiles". Important pices of architecture and sculptures were made in cathedrals in Europe. These include the Cathedral of Chartres and Nicola Pisano's pulpits for the Duomo di Siena and Pisa's Baptistery. In religion, the Sukhothai kingdom in Thailand adopted Buddhism as its official religion. In Europe anti-Semitism became worse because several authorities made laws which said that Jewish people must wear yellow badges so people knew who they were. Many Jewish people were killed in England and the Talmud was attacked and censored by the Catholic Church.
