The 79 individuals were not only suspected of watching or downloading child sexual abuse videos but some of them are suspected of actively participating in abuse.
About 1400 suspects have been identified worldwide.
Europol said the policing operation, which also involved authorities from Australia, New Zealand, the United Kingdom and the United States, was able to protect 39 children.
A platform, known as Kidflix, was taken offline under the leadership of authorities in Bavaria, Germany.
According to Europol, this was one of the world's largest pedophile networks and marks the most extensive operation against child sexual abuse in Europe to date.
The platform's servers with more than 70,000 videos was shut down by German and Dutch authorities at the beginning of March.
The investigation began in 2022 but recently intensified.
Authorities confiscated thousands of electronic devices and more than 91,000 videos between March 10 and March 23.
Europol said Kidflix was set up by cybercriminals in 2021 and became one of the most popular platforms for pedophiles.
On it, users could download and stream videos showing the sexual abuse of children for a fee.
