Thebaud delves into the unique character of the Irish nation, tracing its roots back to ancient times and examining its distinct cultural, religious, and social aspects.

Despite centuries of foreign rule and challenges, the Irish have maintained a strong sense of identity, rooted in their deep Catholic faith and rich cultural traditions. Thebaud argues that Ireland's small size and seeming insignificance on the European stage belie its profound impact and enduring spirit. The book also discusses Ireland's resistance to various European influences, including Protestantism, and how this resistance shaped its national character.

This work is a tribute to the resilience of the Irish people, offering a perspective that views their struggles as a testament to their strength, faith, and unyielding commitment to their heritage.
