The history of Christianity in Europe is long and complex, and there have been many periods of conflict between different Christian factions. However, there has never been a single, definitive "war" between the Church and Christian people in Europe.
One of the most significant periods of conflict was the Reformation, which began in the 16th century. The Reformation was a religious movement that challenged the authority of the Catholic Church and led to the establishment of Protestant churches. This period was marked by religious wars and persecution, as both Catholics and Protestants sought to impose their beliefs on others.
Another significant period of conflict was the French Revolution, which began in 1789. The French Revolution was a political and social upheaval that led to the overthrow of the monarchy and the establishment of a republic. The revolutionaries were hostile to the Catholic Church, which they saw as a symbol of the old order. They seized Church property, closed monasteries, and persecuted priests.
In the 20th century, there were also periods of conflict between the Church and Christian people in Europe. For example, the Spanish Civil War (1936-1939) was fought between Republicans, who were supported by the Catholic Church, and Nationalists, who were opposed to the Church. The Nationalists eventually won the war, and the Church was restored to its former position of power.
Today, there is still some conflict between different Christian factions in Europe. However, there is also a growing movement towards ecumenism, which is the promotion of unity among different Christian churches. This movement is based on the belief that Christians should focus on their shared beliefs rather than their differences.
In conclusion, there has never been a single, definitive "war" between the Church and Christian people in Europe. However, there have been many periods of conflict between different Christian factions. These conflicts have been motivated by a variety of factors, including religious differences, political power struggles, and social upheaval.
