  The state atheism of the former Eastern Bloc, which brought about a persecution of Christians, caused a rise in Christian nationalism in the West, as well as ecumenical cooperation among Christians across denominational lines. For example, the United States, in 1956, adopted " In God We Trust " as its official motto "to differentiate itself from the Soviet Union, its Cold War enemy that was widely seen as promoting atheism." During this time, Christian human rights non-governmental organisations, such as Voice of the Martyrs, were founded in order to provide support to Christians persecuted in the Communist Bloc, also engaging in activities such as Bible smuggling. In the 1990s, the period surrounding the collapse of the Soviet Union led "a surge in the activity of religious groups and interests among broad segments of the population". The revival of the Church occurred in these formerly Communist areas; Christian missionaries also entered the former Eastern Bloc in order to engage in evangelism there, winning people back to Christianity.
  
  Christian democracy is a centrist political ideology inspired by Catholic social teaching and Neo-Calvinist theology. Christian democratic political parties came to prominence after World War II after Roman Catholics and Protestants worked together to help rebuild war-torn Europe. From its inception, Christian Democracy fosters an "ecumenical unity achieved on the religious level against the atheism of the government in the Communist countries".
