[1] Among countries regarded as suitable for Polish overseas settlements, were such nations as Brazil (Paraná), Peru, Liberia, Portuguese Mozambique and French possessions in Africa, such as Madagascar.

On 1 October 1918, a group of 25 young men founded an organization called Polska Bandera (Polish Flag), whose purpose was to popularize the sea among the Poles and to encourage the youth to participate in naval navigation.

[3] Furthermore, some Polish politicians argued that the debt, which the world apparently owed to Poland for allegedly ‘saving’ Europe from communist invasion, should be paid off with colonies.

Among people who participated in demonstrations were clergymen and members of the governing party, Camp of National Unity (Oboz Zjednoczenia Narodowego), accepted colonial aspirations.

[1] However, Poland never considered the possibility of armed capture of overseas lands, counting on a customs union with smaller and less significant colonial powers, such as Belgium and Portugal.

[4] Some historians have argued that the Polish government promoted colonialism to solve the problem of chronic overpopulation and unemployment of some areas of the country.

In June 1934 the League sent its messenger, retired general Stefan Strzemieński, who wanted to buy 2 million hectares of land in Brazilian state of Paraná (part of its population, around 100,000, had already been Polish, due to mass emigration of Poles from Galicia in the 19th century).

[7] Soon afterwards, the Brazilian government under Getúlio Vargas began limiting Polish immigration, and also the Poles themselves were no longer interested in settling in Brazil.

The Black Republic was at the time in danger of becoming a mandate of the League of Nations because of accusations of its ruling Americo-Liberian elite enslaving the indigenous population.

Sajous's visit resulted in a Polish delegation headed by the writer and traveler Janusz Makarczyk, which toured West Africa, including Togo and Sierra Leone, in the spring of 1934.

On 28 April, on behalf of the President of the Maritime and Colonial League, General Gustaw Orlicz-Dreszer, Makarczyk signed the preliminary agreement on a bilateral "Treaty of Friendship" with the Liberian Republic.

For example, Liberia was to incur the cost of sending to and educating several men in Poland, which could eventually serve as a Polish-oriented colonial elite back home.

According to one of Makarczyk's later accounts, the treaty was also supposed to include a secret clause that allowed the League to recruit up to 100,000 Liberians to the Polish Army in case of war.

[10] A special interest was shown in Madagascar, with a kind of historical claim provided by the 18th century Polish adventurer Maurice Benyovszky who had spent some years on that island and on one occasion been chosen a ruler by some of its inhabitants.

After World War II, the newly established Polish People's Republic was not interested in colonialism and the organization was reestablished in 1944 as the Maritime League.
