In 1816, the British parliament repealed the temporary income tax that William Pitt the Younger had introduced in 1789 to finance the Napoleonic war. The MPs hated the tax so much that they even agreed that all documents connected with it should be collected, cut into pieces and pulped. When the income tax was reintroduced in Britain in 1842 by Robert Peel, everyone considered it a temporary measure to replenish the depleted exchequer. But despite generations of politicians after Peel promising to abolish it, the tax never went away.
