On June 4, 1989, partly free elections were held to the lower house of Poland’s parliament, the Sejm, and completely free elections to the upper house, the Senate.

The Solidarity opposition movement scored a resounding victory, winning all the seats available to it in the Sejm, and all but one seat in the freely contested Senate.
The vote was a milestone that is seen as triggering a domino effect across the region, culminating in the fall of the Berlin Wall, a symbol of decades of division between Western Europe and the communist East.
The state-run Institute of National Remembrance (IPN) said on Twitter on Sunday that Poles headed to the ballot box in droves 34 years ago in an effort to change their country's political system.
