Triennial Act

The Triennial Act of 1694 in Great Britain was a significant piece of legislation that limited the maximum duration of a Parliament to three years. This act aimed to ensure more frequent elections and greater accountability of elected officials to the electorate. It was a response to concerns about the length of time Parliament could sit without a fresh mandate from the people.

The concept of Parliament's duration has evolved over time. Initially, Parliaments could last indefinitely until the monarch dissolved them. The Triennial Act of 1694 was a step towards regularizing this process. Later, the Septennial Act of 1716 extended this maximum term to seven years, a duration that largely persisted until the Fixed-Term Parliaments Act 2011, which scheduled elections every five years, though with provisions for early elections. The power dynamics between the House of Commons and the House of Lords have also shifted, notably with the Parliament Act of 1911, which curtailed the Lords' veto power and further strengthened the Commons' position.123
