The first Croatian Buddhist group was founded in Zagreb in the 1980's. Several groups have formed since, affiliated with different traditions. Estimates of the number of Buddhists in Croatia vary from 500 to 1,000, depending on the definition. At present, active Buddhist groups are working to establish foundational practices and communities in major cities. Traditions represented presently are Nyingma and Rime (nonsectarian) of Tibetan Buddhism, Shingon and Zen of Japanese Buddhism, and Ch'an of Chinese Buddhism.
