As the Cold War heated up in the 1950s, the United States made decisions on foreign policy with the goal of containing communism. To maintain its hegemony in the Western Hemisphere, the U.S. intervened in Guatemala in 1954 and removed its elected president, Jacobo Arbenz Guzman, on the premise that he was soft on communism.

Mycenaean Greece (or the Mycenaean civilization) was the last phase of the Bronze Age in Ancient Greece, spanning the period from approximately 1600–1100 BCE. It represents the first advanced civilization in mainland Greece, with its palatial states, urban organization, works of art, and writing system.[1] Among the centers of power that emerged, the most notable were those of Pylos, Tiryns, Midea in the Peloponnese, Orchomenos, Thebes, Athens in Central Greece and Iolcos in Thessaly. The most prominent site was Mycenae, in the Argolid, after which the culture of this era is named. Mycenaean and Mycenaean-influenced settlements also appeared in Epirus,[2][3] Macedonia,[4][5] on islands in the Aegean Sea, on the coast of Asia Minor, the Levant,[6] Cyprus[7] and Italy.[8]
The Mycenaean Greeks introduced several innovations in the fields of engineering, architecture and military infrastructure, while trade over vast areas of the Mediterranean was essential for the Mycenaean economy. Their syllabic script, the Linear B, offers the first written records of the Greek language and their religion already included several deities that can also be found in the Olympic Pantheon. Mycenaean Greece was dominated by a warrior elite society and consisted of a network of palace states that developed rigid hierarchical, political, social and economic systems. At the head of this society was the king, known as wanax.
Mycenaean Greece perished with the collapse of Bronze Age culture in the eastern Mediterranean, to be followed by the so-called Greek Dark Ages, a recordless transitional period leading to Archaic Greece where significant shifts occurred from palace-centralized to de-centralized forms of socio-economic organization (including the extensive use of iron).[9] Various theories have been proposed for the end of this civilization, among them the Dorian invasion or activities connected to the "Sea Peoples". Additional theories such as natural disasters and climatic changes have been also suggested. The Mycenaean period became the historical setting of much ancient Greek literature and mythology, including the Trojan Epic Cycle.[10]
