Final answer:
The ultranationalist group formed in Germany to oppose Muslim refugee immigration is PEGIDA (Patriotic Europeans Against the Islamization of the West). This movement reflects a broader European trend of ultranationalist organizations resisting non-European immigration and seeking to maintain ethno-cultural homogeneity.
Step-by-step explanation:
The ultranationalist group that has arisen in Germany to oppose the immigration of Muslim refugees is PEGIDA, which stands for Patriotic Europeans Against the Islamization of the West. PEGIDA has been particularly active since 2014, conducting weekly marches and expressing a staunch opposition to the presence of Islamic religion and culture in Germany. Founded in reaction to the migrant crisis and policies of German Chancellor Angela Merkel, PEGIDA exemplifies a European trend where various groups have capitalized on public fears regarding Muslim immigrants and terrorism.
Ultrantionalist movements like PEGIDA often support extreme nationalism and pursue the creation of ethnically homogeneous societies. They resist non-European immigration and advocate for more conservative social policies, gaining traction in various countries. In Germany, PEGIDA's stance against the influx of refugees aligns with broader European anxieties about cultural and religious changes brought by immigration from Islamic countries.
These groups not only exist in Europe but have counterparts across the globe, including the Nationalist Front of Mexico and the American Freedom Party in the United States, all promoting ideologies focused on resisting globalization and preserving ethnic homogeneity in their respective nations.
