the Corn Laws [the Corn Laws] BrE NAmE noun [pl]
a set of British laws, first introduced in the ↑Middle Ages, which controlled the import and export of grain in order to protect the price of British wheat. They were ↑unpopular in the 19th century when there was a shortage of wheat and the laws were keeping the prices high. Many Members of Parliament owned agricultural land and made large profits from these high prices. In 1846, under pressure from the Anti-Corn Law League, the government changed the laws.
