High Quality Content by WIKIPEDIA articles! The Parliament of Scotland, officially the Estates of Parliament, was the legislature of the Kingdom of Scotland. The unicameral parliament of Scotland is first found on record during the early 13th century, with the first meeting for which a primary source survives (referred to, like the contemporaneous Parliament of England, as a colloquium in the surviving Latin records) at Kirkliston (a small town now on the outskirts of Edinburgh) in 1235, during the reign of Alexander II of Scotland.
