Exiled by the Austro-Hungarian authorities, Ładoś escaped to Switzerland and continued his interrupted studies in Lausanne being politically active in the Polish diaspora at the same time.

Political enemy of Józef Piłsudski, Ładoś lost his post after the coup d’état in May 1926 but quickly was nominated Consul General of Poland to Munich.

Ładoś believed Poland should seek rapprochement with the Soviet Union as a possible ally against Nazi Germany and advocated closer cooperation with Czechoslovakia.

After the German invasion of Poland, Ładoś headed to Romania to join the Polish Government in Exile as a minister without portfolio between 3 October and 7 December 1939.

Due to the German pressure, Ładoś failed to deliver his credential letters and enjoyed a minor status of chargé d'affaires.

[4][5][6] Ładoś himself intervened directly with the Swiss Federal Counselor Marcel Pilet-Golaz to turn a blind eye to the illegal procedure.

[7] Other people included in the clandestine Ładoś Group included Ładoś’ deputy counsellor Stefan J. Ryniewicz and Jews Chaim Eiss and Abraham Silberschein, members of Jewish organizations whose main task was to smuggle lists of beneficiaries and copies of illegally-obtained passports between Bern and German-occupied Poland.

[8] Ładoś also successfully urged in January 1944 the Polish Government in exile to help obtain official recognition of the passports by Paraguay[9] – the fact that finally happened in February 1944.

Instead of coming back to Poland, he decided to stay in Switzerland, where he acted as a special envoy of the legal opposition PSL-party and its leader Stanisław Mikołajczyk.
