Civil wars are merely an indication that even people who are closely related by ethnicity, culture, history, and geography, can have deep and divisive differences. Civil war has also been connected with genocide in many instances, and for many people, it is considered the most shameful kind of war, even though according to the great François Fénelon, “All wars are civil wars, because all men are brothers.”
10 Bosnian War 1992-1995

The Bosnian War was a brutal, complex, and ugly conflict that followed the fall of communism in Europe.In 1991, Bosnia and Herzegovina joined several republics of the former Yugoslavia and declared independence, which triggered a civil war that lasted for four years. Bosnia’s population was a multicultural mix of Muslim Bosniaks, Orthodox Serbs, and Catholic Croats. The Bosnian Serbs, well-armed and backed by neighboring Serbia, laid siege to the city of Sarajevo in early April, 1992. They targeted mainly the Muslim population, but killed many other Bosnian Serbs and Croats with rocket, mortar, and sniper attacks that went on for nearly three and a half years.As shells fell on the Bosnian capital, nationalist Croat and Serb forces carried out brutal “ethnic cleansing” attacks throughout the countryside. Finally, in 1995, UN air strikes and United Nations sanctions helped bring all parties to a peace agreement. Estimates of the war’s fatalities vary widely, ranging from 90,000 to 300,000.
9 Nigerian Civil War 1967-1970

The Nigerian Civil War, also known as Nigerian-Biafran War, was the result of economic, ethnic, cultural, and religious tensions among the various peoples of Nigeria. Like many other African nations, Nigeria was an artificial construct of imperialism—in this case created by the British, who had neglected to consider religious, linguistic, and ethnic differences when they drew up the borders of the new country. The civil war began on July 6, 1967, when Nigerian Federal troops advanced in two columns into Biafra. Nigeria, which won independence from Britain in 1960, had at that time a population of sixty million people consisting of nearly three hundred different ethnic and cultural groups. The war cost Nigeria a great deal in terms of lives, money, and its standing in the world. It has been estimated that up to three million people may have died due to the conflict—mostly from hunger and disease. It was one of the bloodiest civil wars of the last few decades.
8 Thousand Days’ War 1899-1902

The War of a Thousand Days was a Colombian civil war between the Conservative Party, the Liberal Party and its radical factions that resulted over 100,000 deaths, extensive property damage, and national economic ruin.The Liberal Party represented coffee plantation owners and rich merchants who favored a laissez-faire economic policy. Largely excluded from participation in government after the Conservative victory of 1885, they were further distressed by the drastic downturn in the international price of coffee; by 1899, many coffee growers were operating at a loss.During the next three years, disorganized but highly disruptive guerrilla-style warfare raged in the rural areas, with great destruction of property and loss of life. Unable to pacify the countryside by force, the Conservatives finally offered amnesty and political reform in 1902. By November of the same year, the two most important Liberal leaders, Rafael Uribe and Benjamín Herrera, surrendered after negotiating peace treaties which promised amnesty, free elections, and political reform.
7 Sri Lankan Civil War 1983-2009

In April 2011, the UN released a report on human rights violations during the last phase of the twenty-six-year-long Sri Lankan Civil War, in which over 100,000 people lost their lives. The war was fought between the brutally effective Liberation Tigers of Tamil Eelam and the local government, and it is estimated that at least 40,000 civilians died in the five months before the war’s end in May 2009, when the Tigers surrendered.Most locals greeted the end of the civil war in 2009 with jubilation—but although the fighting has stopped, the restoration of the rule of law and the proper investigation of rights abuses and alleged war crimes by both sides has not yet occurred. On February 12, 2013, the UN Human Rights High Commissioner Navi Pillay stated that Sri Lanka has broken its promise to improve human rights, and has failed to investigate wartime atrocities.
6 Angolan Civil War 1975-2002

253 1Jp Warshoot Lr 4The people of Angola fought bravely against occupation and tyranny to gain their independence from imperialist rulers. Unfortunately, right after Angola became a free nation, the local authorities and political wings lusted after power over the newly formed country. Civil war seemed to be inevitable. The chief cause of this war, in the end, was a power struggle between the popular Movement for the Liberation of Angola (MPLA), and the National Union for Total Independence of Angola (UNITA). It was one of the bloodiest and most prolonged civil wars of modern history, lasting for nearly twenty-seven years. The war began immediately after Angola became independent from Portugal in 1975, and finally ended only when Jonas Savimbi, leader of UNITA, was killed by government troops in 2002. The two sides then agreed to a ceasefire, soon to be followed by elections. The war left at least 500,000 people dead, and an economy in ruins.
