In 2003, the U.S. military bombed Iraq’s national seed bank in Abu Ghraib, effectively eliminating hundreds of varieties of indigenous seeds adapted to growing in the drought-prone desert climate. A year later, U.S. law prohibited Iraqi farmers from seed saving. (First published in 2025 by Prism)

#ResistanceRoots Today in history, 1873: Jay Cooke & Company declares bankruptcy, sparking the Panic of 1873. The catastrophic financial crisis lasted longer than the Great Depression and was in many ways more brutal for ordinary people. We can trace who we are today to its economic devastation. /1
“The Rush from the New York Stock Exchange on September 18, 1873,” by Howard Pyle. There are clear parallels between the Panic of 1873 and today. The crisis wasn’t caused by a lack of wealth. It was caused by irrational exuberance over a revolutionary technology: the railroad. Investors poured billions into laying tracks that led nowhere, assuming the boom would never end. The post-Civil War era also saw the rise of the first mega-corporations, which wielded total control over their employees’ lives and wages. A divide opened between struggling farmers and workers and wealthy Eastern bankers. The farmers felt the “coastal elites” and politicians in Washington were rigging the monetary system against them. In short, the Panic of 1873 was the painful birth of modern industrial capitalism. It proved that an unregulated corporate economy could grow spectacularly, but would also crash brutally.
