Germany initiated the first invasion to kick off world war i what nation did they invade

Poland

Explanation:

The German invasion of Poland was a military action of Nazi Germany aimed at annexing the Polish territory. The technical operation, known as "White Case" (in German, Fall Weiss), began on September 1, 1939 and the last units of the Polish army surrendered on October 6 of that same year. It was the trigger of the Second World War in Europe and ended with the Second Polish Republic.

The invasion of Poland was the first of the warlike aggressions that Hitler's Germany would undertake. The Polish army was easily defeated, unable to cope with the superior German troops who were using their famous technique called blitzkrieg ('lightning war'), based on the rapid movement of the armored and the maximum brutally applied firepower. However, the fall of Poland would be accelerated by the subsequent invasion by the Soviet Union on September 17 and the absence of aid from its allies the United Kingdom and France.

The fall of Poland would mean the abrupt fall of the standards of life of its citizens, especially of the Polish Poles, dying 20% of the Polish population existing before the invasion during the occupation.
