The document discusses the rise of nationalism in Europe between the late 18th and mid-19th centuries. It covers several key points:
1) The French Revolution of 1789 was a major catalyst, establishing concepts like the nation, citizenship, and symbols like the tricolour flag.
2) Napoleon standardized laws and administration across much of Europe but faced opposition. Nationalist sentiments grew across the continent.
3) Most of Europe was divided into different ethnic groups that spoke various languages. Nationalist movements aimed to unite these groups into nation states.
4) Several nationalist movements succeeded in the 19th century, most notably the unification of Germany and Italy, which had previously been divided territories.
