In "The Proud Tower: A Portrait of the World Before the War, 1890-1914," Barbara W. Tuchman explores the powerful influence of patriotism on society during the years leading up to World War I. The quote emphasizes how the emotional connection to one's nation can compel individuals to act in defense of their country, often leading to significant historical events. The fervent support for one's nation reflects deep-seated tribal instincts that drive communal belonging and identity.

Tuchman's work illustrates how nationalism was a dominant force shaping political landscapes, cultural norms, and social dynamics of the time. The passionate allegiance to one's homeland contributed to escalating tensions across Europe, setting the stage for conflict. This portrayal of patriotism serves as a reminder of how collective sentiments can unite people around common causes, but also lead to divisive and destructive outcomes in the pursuit of national interests.
