Which events accelerated the rise of aggressive nationalism in Europe after World War I?

The Great Depression in the United States, which triggered a worldwide depression marked by inflation and widespread poverty and competition among European powers to accelerate their economies, which led to large-scale industrialization are two events that accelerated the rise of aggressive nationalism in Europe after World War I.

Nationalism triggered a continental delusion that contributed to the growing mood for war.

Nationalism refers to an intense form of patriotism or loyalty to one's country.

One of the main reason that accelerated the rise of aggressive nationalism in Europe is The Great Depression in the United States. The economic crisis that came from it caused a worldwide economic depression. This depression caused a significant increase in inflation and poverty in many other countries. Many of the problems were in the end, blamed on the immigrants and their descendants, which is one other thing that encouraged the Nationalist speech.
