John Russell, 1st Earl Russell, KG, GCMG, PC, FRS, known by his courtesy title Lord John Russell before 1861, was a British Whig and Liberal statesman who served as Prime Minister of the United Kingdom from 1846 to 1852 and again from 1865 to 1866.
The third son of the 6th Duke of Bedford, Russell was educated at Westminster School and Edinburgh University before entering Parliament in 1813. In 1828 he took a leading role in the repeal of the Test Acts which discriminated against Catholics and Protestant dissenters. He was one of the principal architects of the Reform Act 1832, which was the first major reform of Parliament since the Restoration, and a significant early step on the road to democracy and away from rule by the aristocracy and landed gentry. He favoured expanding the right to vote to the middle classes and enfranchising Britain's growing industrial towns and cities but he never advocated universal suffrage and he opposed the secret ballot.
