Germany is about to celebrate the sixtieth anniversary of its federal constitution. But the NPD, the country's main extreme far-right political party, continues to gain ground. Its strategy is to start with town halls and regional parliaments in order to, one day, reach the national parliament. And it is betting on the young generation in order to get there.

According to figures published in March, 5.2 % of 15-year-old Germans say they belong to an extreme right-wing organisation. At barely 26, Michael Schäfer embodies this new generation. He is not a skinhead in a bomber jacket. But his role in the NPD consists in bringing together small neo-Nazi groups so that they join his party.

And the NPD doesn't skimp on resources: parties, treks, concerts. But behind the festivities, the racist, nationalist and anti-democratic speeches remain the same. According to a report published on Wednesday by the German Home Office, in the past year, right-wing extremist acts of violence have increased by 15.8 percent.
