After the 1911 breakup of the Standard Oil trust, its largest piece, Standard Oil of New Jersey, spread across Latin America, buying concessions and shaping petroleum laws until countries pushed back. The episode also examines its 1929 cartel with I.G. Farben, separating what the record shows, such as the patent pool, the synthetic-rubber delay, and lead transfers, from myths like U-boat refueling.
Historians dispute how far oil interests caused the Chaco War; the 'oil war' thesis is influential but recent scholarship finds broader causes. The U-boat refueling story is not supported by credible history.
