Final answer:
The reduction of religious influence in Europe is an example of secularization, a process influenced by factors like declining family size due to economic and social changes, and the integration of immigrants with different religious practices.
Step-by-step explanation:
The dwindling role of religion in Europe, as reflected by shifts in cultural practices and demographics, is an example of secularization. Secularization refers to the process by which religious influence on thought, behavior, and social institutions decreases as a society becomes more modern. This trend is enhanced by aspects such as declining family size, the cultural integration of immigrants, and evolving social norms.
These changes impact the cultural landscape of Europe, altering traditional practices and holidays due to the diverse belief systems now present. Furthermore, despite individuals' personal religious beliefs, societal structures—such as holidays and governmental policies—inherit religious influences. Yet, with secularization, the influence of these structures on everyday life is on the wane, underlining the transition towards a more secular society.
