Sweden's Constitution of 1772 () took effect through a bloodless coup d'état, the Revolution of 1772, carried out by Gustav III, who had become king in 1771. It established once again a division of power between the parliament and the king. The period came to be known as the Gustavian era. This was a response to a perceived harm wrought upon Sweden by a half-century of parliamentarism during the country's Age of Liberty practiced according to the Instrument of Government (1719), as many members of the Swedish parliament then used to be bribed by foreign powers.
