Ledóchowska settled in Stockholm and started a language school and a domestic science school for girls while there in 1917 published the book "Polonica" in three different languages. In Denmark in 1918 she founded an orphanage and a school of home economics in Aalborg. In 1920 she returned to Poland with 40 other nuns who had joined her in her mission and with permission from Rome changed her independent convent in Pniewy into the Ursulines of the Agonizing Heart of Jesus which she founded on 7 June 1920. It was in Poland that the apostolic nuncio Achille Ratti - future Pope Pius XI - encouraged and blessed her work. In 1928 she founded a religious center in Rome where she had been living for sometime after Pope Benedict XV had invited her to manage the order there at the beginning of that decade. In 1930 she sent 30 nuns to female Polish workers in France. Ledóchowska was a noted orator who often called for and defended the right for Polish independence; she spoke in various forums and often addressed national leaders and fellow nobles from time to time.
