During the Reformation, many of the convents of Dominican nuns were forced to close. One which managed to survive, and afterwards founded many new houses, was St Ursula's in Augsburg. In the seventeenth century, convents of Dominican women were often asked by their bishops to undertake apostolic work, particularly educating girls and visiting the sick. St Ursula's returned to an enclosed life in the eighteenth century, but in the nineteenth century, after Napoleon had closed many European convents, King Louis I of Bavaria in 1828 restored the Religious Orders of women in his realm, provided that the nuns undertook some active work useful to the State (usually teaching or nursing). In 1877, Bishop Ricards in South Africa requested that Augsburg send a group of nuns to start a teaching mission in King Williamstown. From this mission were founded many Third Order Regular congregations of Dominican sisters, with their own constitutions, though still following the Rule of Saint Augustine and affiliated to the Dominican Order. These include the Dominican Sisters of Oakford, KwazuluNatal (1881), the Dominican Missionary Sisters, Zimbabwe, (1890) and the Dominican Sisters of Newcastle, KwazuluNatal (1891).
