Colombia's paper currency in the early 1900s was deeply entangled with the aftermath of the Thousand Days War (1899–1902), one of the most destructive civil conflicts in the country's history. The war had triggered an extraordinary inflationary collapse — the Banco Nacional had printed so aggressively that its notes became nearly worthless, and the institution was formally liquidated in 1894, well before the war ended. The Junta Nacional de Amortización was tasked with managing the resulting monetary wreckage.

Waterlow & Sons produced the physical notes in London; Colombia at this point lacked domestic printing infrastructure capable of producing secure currency.
