In the late 19th century, after the Berlin conference had ended, European empires sailed with their armies to the Horn of Africa. The imperial clouds wavering over Somalia alarmed the Dervish leader Mohammed Abdullah Hassan, who gathered Somali soldiers from across the Horn of Africa and began one of the longest anti-colonial wars ever. The Dervish State successfully repulsed the British empire four times and forced it to retreat to the coastal region. As a result of its successes against the British, the Dervish State received support from the Ottoman and German empires. The Turks also named Hassan Emir of the Somali nation, and the Germans promised to officially recognize any territories the Dervishes were to acquire. After a quarter of a century of holding the British at bay, the Dervishes were finally defeated in 1920, when Britain for the first time in Africa used airplanes to bomb the Dervish capital of Taleex. As a result of this bombardment, former Dervish territories were turned into a protectorate of Britain. Italy similarly faced the same opposition from Somali Sultans and armies and did not acquire full control of parts of modern Somalia until the Fascist era in late 1927. This occupation lasted till 1941 and was replaced by a British military administration.
In what year did the British defeat the Dervishes?
1920

In Scherer's components processing model of emotion, five crucial elements of emotion are said to exist. From the component processing perspective, emotion experience is said to require that all of these processes become coordinated and synchronized for a short period of time, driven by appraisal processes. Although the inclusion of cognitive appraisal as one of the elements is slightly controversial, since some theorists make the assumption that emotion and cognition are separate but interacting systems, the component processing model provides a sequence of events that effectively describes the coordination involved during an emotional episode.
What processes drive the other components processing model processes?
appraisal

In 1954, Eisenhower articulated the domino theory in his outlook towards communism in Southeast Asia and also in Central America. He believed that if the communists were allowed to prevail in Vietnam, this would cause a succession of countries to fall to communism, from Laos through Malaysia and Indonesia ultimately to India. Likewise, the fall of Guatemala would end with the fall of neighboring Mexico. That year the loss of North Vietnam to the communists and the rejection of his proposed European Defence Community (EDC) were serious defeats, but he remained optimistic in his opposition to the spread of communism, saying "Long faces don't win wars". As he had threatened the French in their rejection of EDC, he afterwards moved to restore West Germany, as a full NATO partner.
According to Eisenhower, all of Southeast Asia would become communist if the communist insurgency won in what country?
Vietnam
