The Bell family home was in Cambridge, Massachusetts, until 1880 when Bell's father-in-law bought a house in Washington, D.C., and later in 1882 bought a home in the same city for Bell's family, so that they could be with him while he attended to the numerous court cases involving patent disputes.

One significant part of treaty making is that signing a treaty implies recognition that the other side is a sovereign state and that the agreement being considered is enforceable under international law.

For example, within the United States, agreements between states are compacts and agreements between states and the federal government or between agencies of the government are memoranda of understanding.

What are agreements between states within the United States called?
Output: compacts

Input: Near East
Until about 1855 the words near east and far east did not refer to any particular region. The far East, a phrase containing a noun, East, qualified by an adjective, far, could be at any location in the "far east" of the speaker's home territory. The Ottoman Empire, for example, was the far East as much as the East Indies. The Crimean War brought a change in vocabulary with the introduction of terms more familiar to the late 19th century. The Russian Empire had entered a more aggressive phase, becoming militarily active against the Ottoman Empire and also against China, with territorial aggrandizement explicitly in mind. Rethinking its policy the British government decided that the two polities under attack were necessary for the balance of power. It therefore undertook to oppose the Russians in both places, one result being the Crimean War. During that war the administration of the British Empire began promulgating a new vocabulary, giving specific regional meaning to "the Near East," the Ottoman Empire, and "the Far East," the East Indies. The two terms were now compound nouns often shown hyphenated.

What brought a change in vocabulary?
Output:
The Crimean War
