The major causes for the start and development of the World War II are the expansionism, nationalism, and natural resources.
This war was started because of the territorial appetites of some countries, namely Germany, Italy, and Japan, each them having their own vision and primary goal. Germany wanted to take over all the historic territories where the Germanic people lived, Italy wanted to resurrect the Roman Empire, while Japan wanted to get hold onto parts of Asia that were rich in natural resources as they have very few.
The nationalism led to mass murders on ethnic basis, with Germany and Japan being the biggest contributors to that, killing all the people that they considered as lesser human being or not suitable.
The natural resources were also one of the main reasons. Germany was trying to get to multiple places that were rich in natural resources, especially with oil, which is why the Soviets were attacked, so that Germany can get its hands on Azerbaijan. Japan too wanted and managed to conquer territories that were rich in oil and metals, as well as other natural resources, providing them with basis for further expansion and strengthening.
The discovery of oil in South Sudan sparked the independence movement that eventually led to the division of country.
The Oil was discovered in Bentu and Heglig districts of South Sudan in 1978. The central government in Khartoum took over the oil districts of South Sudan which sparked rebellion in South Sudan and on the other hand South Sudan wanted to have a greater share in oil revenue. It resulted into conflict in Sudan for a long time and ultimately on 11 July 2011 South Sudan attained her Independence and thus lead to division of Sudan.
Answer:
There is a lot of controversy as to whether these explorers should be called heroes due to some of their actions towards the indigenous people in the regions they supposedly "discovered". Christopher Columbus was responsible for the ra-pe, murder, enslavement of thousands of natives on the island of Hispaniola. Many died from smallpox spread to them by the crew.
They sold little girls and forced the natives to mine for gold or die. Over 50k committed mass sui-cide to avoid being killed or enslaved by the Spaniards.
Hispanola had approximately 300k inhabitants when he landed there. Within two years 100k were dead, in the next 50 years the number was down to 300. Each of these men has their own stories of treatment towards the people in the lands they explored. That is why there is question as to whether they should be considered heroes. The question just wants your opinion on the subject.
