The Neogothic Saint Joseph Cathedral in Bucharest was also completed in 1884, and two seminaries were set up (the main seminary was in Bucharest, and the Iaşi-based one was a Jesuit institution created in 1886, notably led by the Polish priest Feliks Wierciński). The Jesuit Mission in Romania was created in 1918, being subordinated to the Order's Province of Belgium, and then to the Southern Province of Poland; it became a Vice-Province in 1927. Romania accommodated various Catholic organizations, including the Institute of the Brothers of the Christian Schools (who operated three Bucharest schools by 1913), the Sisters of Mercy, the Passionists, and the Congregation of Notre-Dame de Sion. Despite this increase in importance, Romania and the Holy See did not formally establish diplomatic relations for several decades. The authorities also refused to allow the Church to create its own college.
