Le Pen and her coalition put immigration at the center of its campaign, which has served as a battleground election issue from the national election to the EP. Tension with France's Muslim population (the largest in western Europe) has risen in the largely secular country in the wake of terror attacks, and controversies over Islamic practices, such as the wearing of burkinis. Security was another major theme of the election, with questions about how the EU can protect citizens from a range of issues including globalization, tech giants, the US and China, or from further waves of immigration. Concerns around immigration policy, partly fueled by the anti-government protests, have resulted in riots, injury, and death, creating a broad sense of instability. In far-right circles, conspiracy theories purporting the Notre Dame fire was a terror-attack kept secret from the people.
