Which historical example illustrates a negative consequence of nationalism?

The genocide during the Holocaust is a significant historical example illustrating a negative consequence of nationalism. In the context of the Holocaust, extreme nationalism fueled an ideology that viewed certain groups, particularly Jews, as inferior or as threats to a so-called pure national identity. This led to systemic discrimination, dehumanization, and ultimately the mass murder of six million Jews, along with millions of others, including Romani people, political dissidents, disabled individuals, and various minority groups.

The Holocaust exemplifies how extreme nationalist sentiments can foster an environment of hate and violence, where the perceived need to protect a nation’s identity overshadows basic human rights and morality. This tragic event remains a powerful reminder of the dangers posed by unchecked nationalism and the importance of promoting tolerance and understanding in diverse societies. While the other choices involve nationalism in different ways, they do not directly illustrate the same level of widespread violence and human rights violations driven by nationalist ideology as the Holocaust does.
