The Kadampa tradition was later promoted throughout Tibet in the 14th century by Je Tsongkhapa and his followers, known as the "New Kadampas". The New Kadampa Tradition - International Kadampa Buddhist Union (NKT-IKBU) - is an association of over 1300 Buddhist Centers and groups that derive their inspiration and spiritual guidance from the example of the ancient Kadampa Masters and from Venerable Geshe Kelsang Gyatso's presentation of Kadampa Buddhism to the modern world.
