At least 100,000 people gathered in Belgrade on Saturday to protest against Serbian President Aleksandar Vucic and his government [2].

The scale of the demonstration indicates a growing wave of domestic opposition to Vucic's administration, driven largely by a youth-led movement seeking systemic political reform.

University students played a central role in organizing the event, which took place in the city's central square [1, 2, 3]. The rally was designed to renew pressure on the president as citizens voiced grievances regarding alleged corruption and the rise of authoritarian rule [1, 2, 3].

Attendance estimates varied across reporting outlets. While some reports described the crowd as consisting of tens of thousands [3], other accounts said at least 100,000 people descended on the capital for the rally [2]. Earlier projections had suggested that thousands of students were expected to attend the weekend event [1].

The protesters demanded significant political change to address the current state of governance in Serbia [1, 2, 3]. The gathering in the city centre served as a focal point for those criticizing the populist president's grip on power, a sentiment echoed by the diverse group of citizens who joined the students [3].

Security remained a primary concern as the massive crowds streamed into the square [3]. Despite the high numbers, the rally focused on the demand for a more transparent and democratic political system in the country [1, 2].

At least 100,000 people gathered in Belgrade on Saturday to protest against Serbian President Aleksandar Vucic.

The mobilization of university students as the vanguard of these protests suggests a generational shift in Serbian politics. By centering the movement on allegations of authoritarianism and corruption, the protesters are attempting to delegitimize the current administration's populist appeal. The significant discrepancy in crowd size estimates highlights the contested nature of the president's popularity, but the presence of such a large volume of people in the capital indicates that the opposition has moved from fragmented complaints to a coordinated mass movement.
