The music comes from Sabaton's Rorke's Drift, a power metal track about the 1879 defence of Rorke's Drift during the Anglo-Zulu War, when a small British garrison faced a much larger Zulu force. Its driving drums and defiant chorus made it a natural fit for battle edits, history memes and dramatic montages, and short excerpts began circulating on soundboards for creators who wanted instant tension. It remains popular because the song turns an outnumbered stand into an anthem, giving even playful videos a sense of scale and resolve.
