What was Napoleon's Continental Blockade and did it work?

The Berlin Decree of November 21, 1806, ordered all European states under French influence to close their ports to British shipping. The Milan Decree of December 17, 1807, extended it to neutral vessels trading with Britain. The blockade lasted until 1814 and ultimately failed: smuggling was endemic, the policy bankrupted French allies more than Britain, and Tsar Alexander I's 1810 withdrawal from the system was a proximate cause of Napoleon's 1812 invasion of Russia.

Did the Smoot-Hawley Tariff cause the Great Depression?

The Smoot-Hawley Tariff Act, signed June 17, 1930, raised US tariffs on more than 20,000 imported goods to historically high levels. Most economists do not consider it the cause of the Great Depression, but the trigger of retaliatory tariffs by Canada, Britain, France, and others that contracted world trade by approximately 65% between 1929 and 1934. Roosevelt's 1934 Reciprocal Trade Agreements Act effectively reversed the policy.

How did the 2022 Russia sanctions actually work?

Following Russia's invasion of Ukraine on February 24, 2022, the EU, US, UK, Canada, and Japan disconnected seven major Russian banks from SWIFT (March 12, 2022), froze approximately $300 billion in Russian central bank foreign reserves, imposed price caps on Russian oil exports (effective December 5, 2022, at $60/barrel), and banned a range of high-technology exports. The measures are the most coordinated economic warfare package since the 1949-1994 CoCom regime.

What is Section 301 and how has the US used it against China?

Section 301 of the Trade Act of 1974 authorizes the US Trade Representative to impose tariffs in response to unfair foreign trade practices. The Trump administration invoked Section 301 in March 2018 to impose tariffs on approximately $370 billion of Chinese imports across four tranches. The Biden administration retained the framework and added new tariffs in May 2024 on electric vehicles (100%), semiconductors (50%), and lithium-ion batteries (25%).

About the Book

On November 21, 1806, in a captured Prussian capital, Napoleon Bonaparte signed a decree ordering every state under French influence to close its ports to British vessels. It was the first attempt in modern history to wage a continent-wide economic war. The Continental System lasted eight years, was systematically evaded by smugglers and neutral shippers, and ultimately bankrupted Napoleon’s allies more than it bankrupted Britain. When Tsar Alexander I withdrew Russia from the system in 1810, the proximate cause of the 1812 Russian campaign was already in motion.

“Weaponized Economy” traces the two-hundred-year arc from the Berlin Decree to the SWIFT disconnection of seven Russian banks on March 12, 2022. The book argues that economic warfare is not a substitute for kinetic warfare — it is a parallel instrument that nations consistently overestimate as a tool of coercion and consistently underestimate as a generator of blowback. It examines the Opium Wars (1839-1842, 1856-1860) as the original case of trade weaponization through gunboat enforcement, the Smoot-Hawley Tariff Act of 1930 as a textbook study in retaliation cascades, the 1949-1994 CoCom export-control regime as a Cold War precedent for today’s semiconductor export controls, and the modern US-China Section 301 tariff series as the world’s largest peacetime economic conflict by dollar volume.

It draws on the US Treasury Office of Foreign Assets Control (OFAC) Sanctions Lists, US Trade Representative Section 301 investigation reports, the European External Action Service sanctions database, Federal Reserve and ECB analyses of the 2022 Russian reserve freeze, CoCom declassified records (released via the National Archives in 1996), and Adam Tooze’s contemporaneous analysis in “Shutdown” and “Crashed” of the post-2008 and post-2020 sanctions regimes.

What You’ll Discover

🇫🇷 Napoleon’s Continental Blockade

The Berlin Decree of November 21, 1806, the Milan Decree of December 17, 1807, the systematic smuggling through Heligoland, and how Russian non-compliance triggered the 1812 invasion that destroyed the Grande Armée.

☕ The Opium Wars and Gunboat Trade

The 1839 Lin Zexu confiscation of British opium stocks at Canton, the 1842 Treaty of Nanjing that ceded Hong Kong and imposed a $21 million indemnity, and the Second Opium War (1856-1860) that opened the Yangtze and legalized the opium trade.

📉 Smoot-Hawley and the Retaliation Cascade

The June 17, 1930 signing, the immediate Canadian retaliation, the British Imperial Preference shift in 1932, and the approximately 65% collapse in world trade between 1929 and 1934.

🚫 CoCom and the Cold War Tech Embargo

The Coordinating Committee for Multilateral Export Controls, founded November 22, 1949, operating quietly until its 1994 dissolution; the 1987 Toshiba-Kongsberg scandal involving submarine-propeller machining technology sold to the Soviet Union.

UN Security Council Resolution 1718 (October 14, 2006) and the subsequent 2270, 2321, 2371, and 2375 expansions; the limits of enforcement when China and Russia retain partial dissent.

⚛️ Iran, the JCPOA, and Maximum Pressure

The 2015 Joint Comprehensive Plan of Action, the US withdrawal of May 8, 2018, and the “maximum pressure” sanctions reimposition — including the secondary sanctions on European firms doing business with Iran.

About the Author

Michael Rodriguez is an investigative nonfiction author who covers the economics of conflict, sanctions regimes, and the political economy of trade restrictions. For Weaponized Economy, he worked from primary historical texts — the Berlin and Milan Decrees in the French National Archives, the Treaty of Nanjing in UK Foreign Office files (FO 17 series), the original Smoot-Hawley Tariff Act in the US Statutes at Large — and contemporary disclosures including the US Treasury Office of Foreign Assets Control (OFAC) Sanctions Lists, the USTR Section 301 investigation reports for the 2018-2024 China actions, the EU Council Decisions establishing the 2022 Russia sanctions architecture, and the declassified CoCom records released by the US National Archives in 1996.

His methodology combines historical reconstruction of sanctions regimes through their founding legal instruments, comparative effectiveness measurement using the Hufbauer-Schott-Elliott “Economic Sanctions Reconsidered” framework, and supply-chain blowback analysis drawing on Federal Reserve and ECB studies of the 2022 reserve freeze. The book argues that nearly every economic-warfare episode produces the same pattern: the imposing power overestimates leverage, the target adapts faster than expected, and the unintended consequences fall more heavily on uninvolved third parties than on either belligerent.

Rodriguez is the author of several investigations in this series, available at michaelrodriguezbooks.com.
