The aim of the article is to present the situation of Poland and Mexico in the years prior to the establishment of bilateral relations. It is reasonable to have a panorama of very particular conditions that determined the existence of these two countries at the beginning of the 1920s. As Poland reappeared on the political map of Europe it encountered significant difficulties in rebuilding its independent existence. These difficulties were both of an international and domestic dimension. The same can be said about Mexico that was entering the new chapter of its history after a bloody revolution that was aimed to change the domestic situation of the country. In this sense, at the beginning of the 1920s both nations can be described as "Nations reborn".
