Religious event
A large number of english speakers all over the world join a new spiritual movement.
Following the beginning of the war between The American Coalition and EU Civil war, a large minority of citizens in both the United States and Great Britain had developed a large distaste for the unnecessary blood shed. A new religion sparked that was an odd mix of Buddhism, new age spirtualism, and some bits and pieces from Christianity. Their message was simple, only true enlightenment is achievable through passivism and helping your brethren. A large collection of these followers moved to Australia to form one of the largest communes in history. The religion was not relegated to just English speakers, but the majority of it's disciples were from Australia, The U.S. and Western Europe.
