The Twenty-Fourth of February 2022 marked the beginning one of the greatest humanitarian crisis in Europe. Within the first six days of the war, the number of Ukrainian refugees exceeded 4 million, which is more than twice the total number of incomers who arrived in Europe during the Syrian migration throughout 2015. Most of them found themselves in Poland; thus, an urgent need for ad hoc humanitarian and systemic aid arose. To cope with the situation, a number of changes to the Polish law were introduced so as to provide help to the refugees (mainly women and children) from Ukraine. To systematise the changes, the authors of the study analysed the legal acts that had been created or amended for the purposes of providing aid to the refugees staying in Poland. The research study has shown that, in the first days following the war's outbreak, the measures of key importance were the grassroot initiatives taken by Polish citizens, but as days went by, systemic aid became indispensable. Moreover, non-standard needs had to be handled due to the fact that the refugees were mainly women and children rather than entire families. In conclusion, the war in Ukraine has shown how important it is to have refugee aid procedures at hand and to have a detailed guidance prepared beforehand.
