Senior missionary couples played an important role in preparing Communist Eastern European countries to accept and recognize The Church of Jesus Christ of Latter-day Saints. Missionary couples were sent into Poland, Hungary, and Yugoslavia to make political contacts, answer questions about the Church, and to be good examples. These missionaries were initially part of the International Mission, and later assigned from the Vienna Austria Mission. The couples often served alone and without guidance for accomplishing their assignments. They also had to work against language limitations. However, they made a positive impression in these countries and paved the way for the establishment of formal missions and proselyting missionaries in these areas.
