William left most government business to his ministers, and spent most of his time outside of his state at his possessions in Oels. After the revolution of 1830, liberal reforms were made and a new constitution was adopted on 12 October 1832. While the number of voters was limited by a system of census suffrage to about 40% of Brunswick's male population, the parliament of Brunswick was granted more rights than in most other German states at the time and the duke's budget and powers were significantly limited.
