10. Second Congo War (1998-2003)
The Second Congo War, also known as the Great War of Africa, was a complex and multifaceted conflict that involved nine African countries and more than 20 armed groups. It was sparked by the overthrow of Mobutu Sese Seko, the longtime dictator of the Democratic Republic of the Congo (DRC), by Laurent-Désiré Kabila in 1997. Kabila soon faced a rebellion backed by Rwanda and Uganda, who accused him of supporting Hutu militias that had committed genocide in Rwanda in 1994. The war quickly spread to neighboring countries, such as Angola, Zimbabwe, Namibia, Chad, and Sudan, who intervened on different sides of the conflict.
The war was characterized by widespread atrocities, human rights violations, and humanitarian crises. Millions of civilians were displaced, killed, or died from disease, starvation, and malnutrition. The war also fueled the illegal exploitation of the DRC’s rich natural resources, such as diamonds, gold, coltan, and timber, by various parties. The war officially ended in 2003 with the signing of a peace agreement and the establishment of a transitional government. However, sporadic violence and instability continue to plague the region to this day.

9. Napoleonic Wars (1803-1815)
The Napoleonic Wars were a series of wars between the French Empire, led by Napoleon Bonaparte, and a coalition of European powers, such as Britain, Russia, Austria, Prussia, and Spain.

Napoleon, a brilliant military leader and politician, rose to power and expanded his empire across Europe and beyond, spreading the ideals of the revolution and challenging the old order. The coalition, fearing Napoleon’s ambition and influence, formed several alliances to contain and defeat him.
The wars spanned over a decade and involved many battles, campaigns, and invasions across Europe, Africa, Asia, and the Americas. Some of the most famous and decisive battles include Austerlitz, Trafalgar, Borodino, Leipzig, and Waterloo. The wars also had a significant impact on the political, social, and cultural landscape of Europe and the world.

The war was interrupted by the Second Sino-Japanese War (1937-1945), in which the KMT and the CPC formed a united front against the Japanese invasion. However, the alliance soon broke down and the civil war resumed after Japan’s defeat in World War II.
The war was marked by ideological, political, and military clashes, as well as foreign intervention and support from the United States and the Soviet Union.
