After three partitions made by Russia, Austria and Germany, Poland completely disappeared from maps for 123 years. Our country regained independence in 1918 after The First World War. In those days Polish people accounted for only 67% of Polish population. There were many people of other nationalities, for example Jews, Germans and Russians. People who lived in Poland were very happy, because they were independent.
At that time Polish economy developed quite slowly. Thing that developed the most quickly was a social life of Polish people. There were many cafes, restaurants and theatres in Polish cities. However, people sensed that the second war is approaching. They were right. This period called "Independent Poland" lasted a very short time. In September 1939 German army invaded Polish lands. It was a beginning of the worst battle in the whole world The Second World War.
