Adolf Hitler started World War II for a number of reasons, including:
Territorial expansion
Hitler wanted to expand Germany’s territory to reunify the German people and create “living space” for Germans to be economically and militarily secure.
Revenge for the Treaty of Versailles
Many Germans resented the harsh terms of the Treaty of Versailles, which ended World War I.
Annexation of Austria and Czechoslovakia
Hitler annexed Austria and Czechoslovakia in 1938β39 with little resistance.
Invasion of Poland
On September 1, 1939, Germany invaded Poland, which had been guaranteed military support by France and Britain. Two days later, both countries declared war on Germany, marking the beginning of World War II.
Hitler rose to power through the Nazi Party, which he formed after returning from World War I. The Nazis’ goals included seizing power through Germany’s parliamentary system, installing Hitler as dictator, and creating a community of racially pure Germans.

Heat us the degree of hotness or coldness of a body.The human body produces heat through a combination of processes, including:
See lessMetabolism
The body metabolizes food to produce heat through chemical reactions and cellular respiration. The liver is a major source of metabolic heat.
Muscle contractions
Involuntary muscle contractions, like shivering, increase muscle cell activity and create heat. Voluntary muscle exertion and motion also produce heat.
Cellular respiration
Cellular respiration produces energy in the form of ATP, which is used for daily activities and the excess is released as heat.
Thyroid hormones
The hypothalamus releases thyroid hormones, which increase metabolic rate and heat production.
Blood friction
The friction of blood against blood vessel walls produces heat.
The body’s temperature is usually between 98 and 110 degrees Fahrenheit. The body’s ability to generate heat helps it resist exposure to low temperatures.
