Rozumní, formerly known as the Party of Common Sense (Czech: Strana zdravého rozumu) was a Czech nationalist political party,[6] led by Petr Hannig.

The party received 0.2% of the vote in the 2002 Czech parliamentary election and failed to reach the 5% threshold for representation.

This electoral alliance ran in the 2009 European election under the name 'Sovereignty', led by Bobošíková.

The list came fifth, winning 4.3% of the vote, just short of the 5% threshold for representation.

In 2010, the party changed its name to Sovereignty – Party of Common Sense (Suverenita – Strana zdravého rozumu), and won 3.7% in the 2010 election, again falling short of parliamentary representation.
