corn laws, regulations restricting the export and import of grain, particularly in England. As early as 1361 export was forbidden in order to keep English grain cheap. Subsequent laws, numerous and complex, forbade export unless the domestic price was low and forbade import unless it was high. The purpose of the laws was to assure a stable and sufficient supply of grain from domestic sources, eliminating undue dependence on foreign supplies, yet allowing for imports in time of scarcity. The corn law of 1815 was designed to maintain high prices and prevent an agricultural depression after the Napoleonic Wars. Consumers and laborers objected, but it was the criticism of manufacturers that the laws hampered industrialization by subsidizing agriculture that proved most effective. Following a campaign by the Anti-Corn-Law League, the corn laws were repealed by the Conservative government of Sir Robert Peel in 1846, despite the opposition of many of his own party, led by Lord George Bentinck and Benjamin Disraeli. With the revival of protectionism in the 20th cent., new grain restriction laws have been passed, but they have not been as extensive as those of earlier times.
