This is normally due to religious differences, and tension which eventually boil over into all out war. Thousands or even millions of people will give their lives in wars based around ideology.

French Catholics and Protestants fought many battles, from the years of 1562 to 1598. The flames of war were lit in 1562 after the Massacre of Valley. Armed troops of Francais, Duke of Guise massacred protestant worshippers and citizens. The massacre started when the Duke was travelling and encountered a large group of protestants outside of a church. He tried to push his way through the crowd and a conflict began. A stone was thrown and hit him in the head. This pushed him over the edge and he gave orders for the whole town to be fortified and the church to be burnt to the ground. The massacre killed 63 people, injured over a 100, and led to a series of bloody French holy wars.

It was the one of the longest holy wars in history, and few holy wars have caused as much death and devastation as this one. Up to 4 million people died in the series of battles, and conflicts but eventually the war that started in 1618 ended in 1648.

The Crusades were a long series of Holy wars that began for a large variety of reasons. Three of the main reasons were the recapture of Jerusalem, recapture of Christian territory, and to protect Christians being attacked in land outside of Christian territory. It started when Pope Urban II issued a call to arms to support the Byzantine empire who were facing off with Turks in Anatolia, who would later establish the Ottoman Empire. This is one of the most famous and controversial holy wars in history. The Crusades shaped the west in a significant way, it reopened the Mediterranean to commerce and travel, allowed many European cities to flourish, and changed the way we view medieval Europe.

The war started because of religious controversy on Luther, but other contributing factors may have been potential loss of rights, and centralising nation state. Over 300,000 peasants revolted but the rebellion was quickly destroyed by the aristocracy who mercilessly killed over 100,000 of the peasants. After that several other revolts would continue to break out lead by farmers and peasants. It started in 1524, lasted for 1 year, and finally ended with the suppression of the rebelling peasants in 1525.

England, and the Soviet Union backed the federal state, where as France backed Biafra. Biafra lost the war and the majority of their troops. They rejoined Nigeria as a result of the loss.
