BUCHAREST, Romania — Exactly one week after the largest protests in a quarter of a century rocked Romania, an estimated 70,000 demonstrators filled the square outside the main government building in Bucharest on Sunday evening, determined to show those in power that the crisis was far from over.

While significantly less than the half a million who took to the streets across the country the previous Sunday, the Bucharest demonstration was still a potent sign of the resilient unrest in the country and the loss of trust between the new government, only in office since the beginning of January, and a large sector of the population.

Sunday was the 13th night in a row that protesters occupied Piata Victoriei — Victory Square — in Bucharest, after the government passed an emergency ordinance on Jan. 31 that effectively decriminalized some low-level corruption offenses, including cases of official misconduct in which the financial damage was less than 200,000 lei, or about $47,000. Protests have also taken place in more than 50 towns and cities across the country.

In the face of the large-scale backlash, the emergency ordinance was repealed a week ago, but that has not stopped protesters from demonstrating their anger.
