Instrument of Government (1719)

The 1719 Instrument of Government (Swedish: regeringsform) adopted on 21 February 1719 by the Riksdag of the Estates (Swedish parliament), was the constitution of the Kingdom of Sweden from 1719 to 1720. Although only in force for a few months, it has great significance in Swedish history, as its promulgation marked the end of the country's first period of absolutism (1680-1719) and the beginning of the period of constitutional monarchy and parliamentary government traditionally known as the Age of Liberty.
