Answer:
Many empires were the result of military conquest, incorporating the vanquished states into a political union, but imperial hegemony can be established in other ways. The Athenian Empire, the Roman Empire, and the British Empire developed at least in part under elective auspices.
Explanation:
Unions protect workers from various company abuses such as unsafe/uncomfortable working conditions, long hours, arbitrary hiring & firing, and so on.
They give workers a chance to speak at the same negotiating & power levels of the managers and owners.
They allow workers to collectively bargain for wages, benefits, an acceptable work environment, and more.
Unions prevent managers from having to address worker grievances one-by-one.
Unions give workers more job security and piece of mind, reducing the stress of possible layoffs & wage/benefit cuts.
Unions create a stable, long-term employment relationship between company and employee, which is good for both.
Unions lead to higher prices for consumers since companies must pay more for wages & benefits, which are then passed on to customers.
Unions make the country less competitive since non-unionized companies in India, China, Taiwan, etc. can pay workers far less and therefore charge less and/or assign more workers per unit of product

The most common form of rule in world history has been monarchy (from the Greek <em>monos</em>, "one," and <em>arche</em>, "power"). It is an unipersonal, hereditary and lifelong form of government. The Head of State is the king (or queen), the prince or the emperor. Although monarchy was at first absolute (the ruler had absolute or total power), it then evolved into a limited form (the ruler needed the help of the most powerful members of society) and finally into a constitutional form (the ruler is primarily a symbolic figure and the nation is governed by a parliament).
At present, the monarchy is the form of government of a few countries around the world, such as Spain, England, Japan and Denmark, to name a few.
