Liberum veto

The liberum veto was a parliamentary rule of the Polish-Lithuanian Commonwealth allowing any single deputy of the Sejm to dissolve the session and annul its legislation. It reflected the nobility's commitment to unanimity and liberty. From the mid-seventeenth century its frequent use paralysed government and allowed foreign powers to manipulate Commonwealth politics, contributing to its decline.
