Wolfram argues that Gothic identity wasn't about bloodline but about loyalty to a small military elite (the Gens ) that carried the tribe's names and myths.
The Goths left a lasting legacy in European history, particularly in the fields of art, architecture, and literature. Gothic architecture, which emerged in the 12th century AD, was characterized by the use of pointed arches, ribbed vaults, and flying buttresses. The Goths also contributed to the development of the Germanic languages, including English, German, and Dutch.

But History of the Goths remains his magnum opus: 580+ densely packed pages (in the English edition) tracing the Goths from their legendary origins in Scandza (Scandinavia) to their disintegration under Byzantine reconquest and Arab expansion.
