William was the second son of Frederick William, Duke of Brunswick-Lüneburg, and after the death of his father in 1815, was under the guardianship of King George IV of the United Kingdom. He became a Prussian major in 1823. When his brother, Charles, was deposed as ruling duke by a rebellion in 1830, William took over the government provisionally. In 1831, a family law of the House of Guelph made William the ruling duke permanently. William left most government business to his ministers, and he spent most of his time outside of his state at his possessions in Oels.
While William joined the Prussian-led North German Confederation in 1866, his relationship to Prussia was strained, since Prussia refused to recognize Ernest Augustus, Crown Prince of Hanover, his nearest male-line relative, as his heir, because of the Duke of Cumberland's claim to the throne of Hanover. William died in 1884; he passed on his private possessions to the Duke of Cumberland. His death caused a constitutional crisis for Brunswick that lasted until the accession of Ernest Augustus, Duke of Brunswick, the son of the Crown Prince of Hanover, in 1913.
William died unmarried, but had a number of illegitimate children.
