Around 50,000 joined an anti-corruption march in the Romanian capital of Bucharest on Saturday.
Thousands more demonstrators also took to the streets in large cities across the country, including in the Cluj, Timisoara, Constanta, Bacau, Sibiu and Iasi.
Euronews’ Hans Von der Brelie talked to protesters in and around Bucharest during the demonstration. You can watch this live coverage of the demonstrations below.
Protesters were upset about government moves that they said would put the justice system partially under political control.
The legislation has been passed by Romanian MPs and is currently with President Klaus Iohannis for approval.
Protesters were also against moves to decriminalise some lower-level corruption offences - a battle that has been going on for a year.
Young and old turned out to show their outrage at the left-wing government, yelling: "Thieves, thieves!" and "Resign!"
There were brief scuffles between demonstrators and riot police as crowds gathered in Bucharest's University Square.
Demonstrators then marched toward Parliament blowing whistles and waving Romanian flags.
