the tasks of party organization; hence they grew steadily weaker as the political triumphs of the Republican Party grew. For economic and philosophical reasons, the Federalists tended to be pro-British—the United States engaged in more trade with Great Britain than with any other country—and vociferously opposed Jefferson's Embargo Act of 1807 and the seemingly deliberate provocation of war with Britain by the Madison Administration. During "Mr. Madison's War", as they called it, the Federalists made a temporary comeback. However, they lost all their gains and more during the patriotic euphoria that followed the war. The membership was aging rapidly, but a few young men from New England did join the cause, most notably Daniel Webster. After 1816, the Federalists had no national power base apart from John Marshall's Supreme Court. They had some local support in New England, New York, eastern Pennsylvania, Maryland and Delaware. After the collapse of the Federalist Party in the course of the 1824 presidential election, most surviving Federalists (including Daniel Webster) joined former Republicans like Henry Clay to form the National Republican Party, which was soon combined with other anti-Jackson groups to form the Whig Party in 1833. By then, nearly all remaining Federalists joined the Whigs. However, some former Federalists like James Buchanan, Louis McLane and Roger B. Taney became Jacksonian Democrats. The "Old Republicans", led by John Randolph of Roanoke, refused to form a coalition with the Federalists and instead set up a separate opposition since Jefferson, Madison, Gallatin, Monroe, John C. Calhoun and Clay had in effect adopted Federalist principles of implied powers to purchase the Louisiana Territory and after the failures and lessons of the War of 1812 raised tariffs to protect factories, chartered the Second National Bank, promoted a strong army and navy and promoted internal improvements. All these measures were opposed to the strict construction of the Constitution, which was the formal basis of the Republicans, but the drift of the party to support them could not be checked. It was aided by the Supreme Court, whose influence under John Marshall as a nationalizing factor now first became apparent. The whole change reconciled the Federalists to their absorption into the Republican Party. Indeed, they claimed, with considerable show of justice, that the absorption was in the other direction: that the Republicans had recanted and that the "Washington-Monroe policy", as they termed it after 1820, was all that Federalists had
