Eventually, sixty-four (64) branches of temples, ashrams, and mathas were established, with the Chaitanya Gaudiya Math as the flagship math of Bhaktisiddhanta Sarasvati Thakura. An effort was made to preach to European countries by the Gaudiya Math in the 1930s (led by Bhaktisiddhanta's disciple Swami Bon Maharaj) which resulted in a handful of longtime adherents, such as E.G.Schulze of Germany, who became Sadananda Swami, and later, Walther Eidlitz of Austria, who became Vamana dasa.citation needed
Break up
With Bhaktisiddhanta's death in 1937, the mathas and disciples lost the cohesiveness and unity that they once enjoyed during his life of preaching. The disciples of Bhaktisiddhanta founded their own mathas and organizations and became acharyas.citation needed
