During which years was the Liberal Party in power alone?

The years 1905 to 1915 marked a significant period for the Liberal Party in the UK, as they held power alone during this time. Under Prime Minister Henry Campbell-Bannerman and later H. H. Asquith, the Liberal government focused on various reforms, including social welfare measures and changes to the House of Lords.

During this era, the Liberal Party was able to implement key legislation such as the Education Act of 1906 and the National Insurance Act of 1911, which were substantial strides towards establishing a welfare state. The period also saw the introduction of policies aimed at addressing issues such as health, employment, and social justice.

In contrast, the other time frames do not align with periods of exclusive Liberal governance. Prior to 1905, the Liberal Party shared power or was dominantly challenged by the Conservative Party. After 1915, the Liberal Party was part of a wartime coalition government due to World War I, which involved other political parties.
