By the early 20th century, some historians, such as Arnold J. Toynbee, were attempting to construct multifocal models of world civilizations. Toynbee also drew attention in Europe to non-European historians, such as the medieval Tunisian scholar Ibn Khaldun. He also established links with Asian thinkers, such as through his dialogues with Daisaku Ikeda of Soka Gakkai International.[15]
