1788 Polish-Lithuanian legislative election

The 1788 election held in the Polish–Lithuanian Commonwealth marked one of the most crucial events in the history of both countries prior to 1795. The elections returned a significant pro-reform camp to the Sejm of the Polish–Lithuanian Commonwealth chosen to repair the Commonwealth's political system and prevent the country from collapsing. The Sejm that emerged as a result of the election has been dubbed the Great Sejm.
