Under which act did Scotland start to receive devolved powers?

Scotland began to receive devolved powers under the Scotland Act 1998. This significant piece of legislation established the Scottish Parliament, granting it the authority to legislate on a range of domestic issues such as health, education, and justice. The act was a key component of the devolution movement in the UK, intended to address public demand for more local governance and to recognize Scotland's unique national identity.

The Scotland Act 1998 marked a transformative moment in the governance of Scotland, allowing for greater autonomy from the UK Parliament in Westminster. It laid the groundwork for subsequent developments in devolution, including further powers being granted over time, reflecting the ongoing evolution of Scotland's administrative landscape.

The other options relate to different contexts and outcomes. For instance, the Government of Wales Act 2006 deals specifically with Wales and its own devolution process, while the Acts of Union and the Parliament Acts pertain to historical agreements and parliamentary procedures that do not directly relate to the establishment of the Scottish Parliament or the devolution of powers to Scotland.
