Subsequently, the Roman Catholic presence registered significant successes: new religious institutes, such as the Assumptionists and the Sisters of St. Mary, began their activities on Romanian soil, and the lay "Acţiunea Catolică", a Romanian version of the Catholic Action, was set up in 1927. By the end of World War II, there were 25 religious institutes present in the country in 203 monasteries, maintaining 421 religious schools and coordinating various charity ventures. Over the early 1920s, the Holy See and Romania engaged in several diplomatic disputes: in one case, the Catholic Church declared itself dissatisfied by the effects of a land reform carried out in 1920–1921 (as a result of talks, it was occasionally allowed to keep larger estates than the law permitted); in parallel, Romanian authorities were dissatisfied with the activities of certain Roman Catholic prelates in Transylvania and Hungary, whom they suspected of actively supporting Hungarian irredentism (in one of his notes to the Vatican, Pennescu condemned the politically motivated letters addressed by Gyula Glattfelder, the Bishop of Timișoara, to his Hungarian-majority congregation).
