Most civilizations have practiced some form of slavery in their development. Famine or fear of stronger enemies might force one tribe to ask another to help and give themselves in a type of bondage in exchange that was similar to the European serf system. 
Arabs also had slave trading, they exchanged slaves for goods from other parts of the world. 
Until that moment, slavery was not linked to color, it was mostly linked to war and economic opportunities.
Slavery became a matter of color when Portugal started to explore the West Coast of Africa in 1444. Because African slaves were identified by their skin color since then, slavery became a matter of color and not economic opportunities or war. Europeans settled in Brazil, Caribbean, and North America and developed a system of racially based slavery.

Answer:
Explanation:
On 22 June 1941, Hitler launched an invasion of the Soviet Union. Stalin was confident that the total Allied war machine would eventually stop Germany, 
and with Lend Lease from the West, the Soviets stopped the Wehrmacht some 30 kilometers (or 18.6 miles) from Moscow. Over the next four years, the Soviet Union repulsed Axis offensives, such as at the Battle of Stalingrad and the Battle of Kursk, and pressed forward to victory in large Soviet offensives, such as the Vistula–Oder Offensive.
The bulk of Soviet fighting took place on the Eastern Front—including a continued war with Finland—but it also invaded Iran (August 1941) in cooperation with the British and late in the war attacked Japan (August 1945), with which the Soviets had border wars earlier up until in 1939.

Answer:
Otto Von Bismarck is remembered as the Iron Chancellor. He was an outstanding diplomat who did much for the unification and economy of the German nation. But while he did favor diplomacy he also resorted to war on some occasions to unite the Germans and to expand the country's borders. So the first half of the sentence refers to diplomacy, and the other half refers to war since iron is for weapons and blood is for lives that are lost for new territory.
