Article: The Cold War saw periods of both heightened tension and relative calm. International crises arose, such as the Berlin Blockade (19481949), the Korean War (19501953), the Berlin Crisis of 1961, the Vietnam War (19591975), the Cuban Missile Crisis (1962), the Soviet war in Afghanistan (19791989) and NATO exercises in November 1983. There were also periods of reduced tension as both sides sought detente. Direct military attacks on adversaries were deterred by the potential for mutual assured destruction using deliverable nuclear weapons. In the Cold War era, the Generation of Love and the rise of computers changed society in very different, complex ways, including higher social and local mobility.

Here is a question about this article: The American Civil War boosted the local economy with wartime purchases of industrial goods, including that of the New Haven Arms Company, which would later become the Winchester Repeating Arms Company. (Winchester would continue to produce arms in New Haven until 2006, and many of the buildings that were a part of the Winchester plant are now a part of the Winchester Repeating Arms Company Historic District.) After the war, population grew and doubled by the start of the 20th century, most notably due to the influx of immigrants from southern Europe, particularly Italy. Today, roughly half the populations of East Haven, West Haven, and North Haven are Italian-American. Jewish immigration to New Haven has left an enduring mark on the city. Westville was the center of Jewish life in New Haven, though today many have fanned out to suburban communities such as Woodbridge and Cheshire.
What is the answer to this question: The Civil War had many effects after the war, what was the main effect for New Haven?
****
So... population grew and doubled

Another theory describes its derivation from a non-Slavic warrior class,:42, 6466 forming a distinct element known as the Lechici/Lekhi (Lechitow):430 :482 within the ancient Polonic tribal groupings (Indo-European caste systems). This hypothesis states this upper class was not of Slavonic extraction:482 and was of a different origin than the Slavonic peasants (kmiecie; Latin: cmethones):430 :118 over which they ruled.:482 The Szlachta were differentiated from the rural population. The nobleman's sense of distinction led to practices that in later periods would be characterized as racism.:233 The Szlachta were noble in the Aryan sense -- "noble" in contrast to the people over whom they ruled after coming into contact with them.:482 The szlachta traced their descent from Lech/Lekh, who probably founded the Polish kingdom in about the fifth century.:482 Lechia was the name of Poland in antiquity, and the szlachta's own name for themselves was Lechici/Lekhi.:482 An exact counterpart of Szlachta society was the Meerassee system of tenure of southern Indiaan aristocracy of equalitysettled as conquerors among a separate race.:484 The Polish state paralleled the Roman Empire in that full rights of citizenship were limited to the szlachta. The szlachta were a caste, a military caste, as in Hindu society.

Gaddafi briefly studied History at the University of Libya in Benghazi, before dropping out to join the military. Despite his police record, in 1963 he began training at the Royal Military Academy, Benghazi, alongside several like-minded friends from Misrata. The armed forces offered the only opportunity for upward social mobility for underprivileged Libyans, and Gaddafi recognised it as a potential instrument of political change. Under Idris, Libya's armed forces were trained by the British military; this angered Gaddafi, who viewed the British as imperialists, and accordingly he refused to learn English and was rude to the British officers, ultimately failing his exams. British trainers reported him for insubordination and abusive behaviour, stating their suspicion that he was involved in the assassination of the military academy's commander in 1963. Such reports were ignored and Gaddafi quickly progressed through the course.

What country trained Libya's military?
Answer: the British military
