The Nazi Party (often shorted simply to "Nazis") were the ruling party of Germany during the events of World War II
and became infamous as a society that, under the control of Adolf Hitler, orchestrated a number of unlawful invasions as well as atrocities such as the Holocaust and Blitz.
The Nazi Party have become a staple symbol of evil in the minds of many along with their symbol, the Swatzika, which is outlawed in a few countries as a hate symbol - the Nazi Party was part of a wider network of regimes collectively known as the Axis Powers during World War II and ultimately found defeat shortly after Hitler committed suicide.
Although extensive work was done to try and remove Nazi heritage from Germany and surrounding areas there are still a few Neo-Nazi groups in existence and many far-right factions are labeled "Nazis" by their opponents (whether or not they actually practice Nazism in the strictest sense of the word).
