The 1901 US stock-market panic triggered by a control fight over the Northern Pacific Railway was the Panic of 1901.
The struggle involved financier Edward Harriman and the investment group associated with James J. Hill and J. P. Morgan. Investors bought Northern Pacific shares aggressively while competing to gain control of the railroad. The share price rose to extraordinary levels before the supply of available stock became severely limited.
On May 9, 1901, Northern Pacific shares plunged, and the panic spread to other railroad stocks. The episode caused heavy losses for speculators and demonstrated how concentrated ownership and margin trading could destabilize markets. Morgan’s interests and Harriman eventually reached an accommodation rather than allowing the confrontation to destroy the railroad.
The Panic of 1901 is often confused with the Panic of 1907, which produced a broader banking crisis and helped motivate the creation of the Federal Reserve. The 1901 event was primarily a railroad-control battle centered on one company’s shares.
