Abstract: In the 18th century，the Society of Jesus developed into an enormous international religious order. Unfortunately in 1773，over 200 years since its foundation，it was suppressed by Pope Clément XIV by the promulgation of the papal brief-Dominus ac Redemptor after encountering much criticism for its submission to the leadership of the Roman Curia and the missionary work it carried out overseas. The incident prompted the Portuguese and the Roman Congregations for the Propagation of the Faith who had long-standing conflicting interests in China to grab the property used to belong to the French mission in Peking. To protect them from being snatched by other countries，the former members of the Jesuits in conjunction with the French Emperor and some ministers started a hard-won battle over the ownership of these properties that took over a decade and engaged stakeholders across two continents. Thanks to their consistent efforts，the Roman Congregations for the Propagation of the Faith eventually approved in 1783 that the French mission in Peking should be taken over by the French Congregation of the Mission ( Lazarists) . In 1814，the Society of Jesus was reinstated by Pie VII and in 1842 members of the Society was dispatched back to China and the Mission of Peking has remained the responsibility of the French Congregation of the Mission ever since.
