As you may know, it is estimated that close to 18 million people lost their lives during World War I and that number jumped to approximately 70 million during World War II. However, History has been the scene of countless bloody conflicts, and we at Mega Curioso have gathered 5 of them - from a selection of Petr Habarta from the List25 portal - for you to check. Look:

1 - The Siege of Jerusalem

The siege of Jerusalem took place in the year 73 and had an estimated death toll of 1.1 million people. The conflict was a defining event of the First Roman-Jewish War and occurred when the Roman army besieged and conquered Jerusalem - which had been occupied by Jewish defenders.

Estimated death: 1.1 million people

The siege ended with the Romans plundering and dominating the city and the destruction of the Second Temple, built by the Jews after their return to Jerusalem - after their exile in Babylon - in the same place where Solomon's ancient Temple once stood.

2 - Tamerlane Achievements

The Achievements of Tamerlane, a Turkish-Mongol Muslim conqueror and military leader, occurred between the 14th and 15th centuries and resulted in the deaths of an estimated 8 to 20 million people, depending on the source consulted.

Estimated deaths: between 8 and 20 million people

In just over 20 years, Tamerlane conquered no less than 8 million square kilometers and became one of the greatest rulers of the Muslim world. During this time, his armies crossed Eurasia from Delhi to Moscow and from the Tian Shan mountain range in Central Asia to the Tauro Mountains in Anatolia, across Persia, Iraq and Armenia, razing, conquering and regaining everything in their path. .

3 - Conquest of the Americas

Although the process of European colonization of the Americas technically began between the 10th and 11th centuries with the brief establishment of Viking settlements on the coast of Canada, it was not until 1492, when Christopher Columbus arrived here with the Spanish, that Achievements have really begun.

Estimated deaths: between 8.5 and 138 million people

Given the lack of consensus on the number of people living in the Americas before the arrival of the Spanish conquerors, there is a huge debate about how many people died during the nearly 200 years of fierce wars and battles between settlers and natives. However, estimates show that between 8.5 and 138 million people lost their lives.

4 - Three Kingdoms War

The Three Kingdoms War consisted of a series of armed conflicts that took place in China between 220 and 280. During this period, three kingdoms - the Wei, the Wu and the Shu - struggled to unify the dynasties, to create one nation and see who would be in charge of everything, of course.

Estimated deaths: between 36 and 40 million people

As a result, the Three Kingdoms War became known as one of the most violent periods in Chinese history, and estimates indicate that the countless - and brutal - battles fought led to the deaths of an estimated 36 to 40 million people.

5 - Mongol Achievements

The Mongol invasions and conquests took place mainly during the 13th century, and by the turn of the following century, the Mongol Empire already occupied much of Asia and eastern Europe. Of course, this whole domination did not come about through friendly negotiations and agreements!

Estimated deaths: 40 to 70 million people

According to historians, the Mongol Achievements are among the most atrocious conflicts in the history of human civilization, and an estimated 40 to 70 million people died as a result of the invasions.
