Recently looked up the biggest 3 tariffs in the US History to compare to the first group of tariffs put into effect by ***** on Feb 1, 2025. The difference were most were enacted by Congress as was more typical, but also done during summer when Congress was likely on break. See below: Tariff of Abominations of May 1828, Dingley Act of June 1897, and the Smoot-Hawley Act of July 1930, And *****'s Tariff Acts of Feb 2025.



Smoot-Hawley Act, June 17, 1930 (Herbert Hoover, sitting President)

Thanks for posting this information Jennifer. I took the liberty of making a synastry chart for the US Sibley Chart with each of the the charts for the tariff acts. I included the smoot hawley act in 1930 and the liberation day created by ***** on April 2, 2025. I will upload these charts as well and then make some comments on what sticks out to me. This is great info. Thanks again!
