It is possible to regard the embargo policy dispassionately as an interesting illustration of Jefferson's love of peace.
Her leading politicians were out of sympathy with the conduct of national affairs (in the conduct of foreign relations, the distribution of political patronage, naval policy, the question of public debt) from 1804 - when Jefferson's party showed its complete supremacy - onward; and particularly after the passage of the Embargo Act of 1807, which caused great losses to Massachusetts commerce, and, so far from being accepted by her leaders as a proper diplomatic weapon, seemed to them designed in the interests of the Democratic party.
It was Boston commerce that was most sorely hurt by the embargo and non-importation policy of President Jefferson.
When news of the embargo of the port at Boston arrived at New Haven, a Committee of Correspondence was at once formed; and in the War of Independence the people enthusiastically supported the American cause.
Commercial interests have been almost entirely destroyed, partly because of the abolition of the slave trade and partly because of the embargo and the war of 1812, but mainly because the cities of the state are unfavourably situated to be the termini of interstate railway systems. Providence, owing to its superior water-power facilities, has therefore become one of the leading manufacturing centres of New England, whereas Newport is now known only as a fashionable summer resort.
He now laid an embargo upon Megara by which the Megarians were forbidden on pain of death to pursue trading operations with any part of the Athenian Empire.
It was a notorious place for smuggling under the Embargo Acts of 1807 and 1808.
An embargo on trade with Flanders, voted in 1358 by a general assembly, resulted by 1360 in the full restoration of German privileges in Flanders, but reduced the counter at Bruges to an executive organ of a united town policy.
The War of 1812, with the Embargo Acts (1807-1813), which were so destructive of New England's commerce, thoroughly aroused the Federalist leaders in this part of the country against the National government as administered by the Democrats, and in 1814, when the British were not only threatening a general invasion of their territory but had actually occupied a part of the Maine coast, and the National government promised no protection, the legislature of Massachusetts invited the other New England states to join with her in sending delegates to a convention which should meet at Hartford to consider their grievances, means of preserving their resources, measures of protection against the British, and the advisability of taking measures to bring about a convention of delegates from all the United States for the purpose of revising the Federal constitution.
This outrageous demand was followed by three others - that the Athenians should (I) withdraw from Potidaea, (2) restore autonomy to Aegina, and (3) withdraw the embargo on Megarian commerce.
