Ancient Greeks distinguished between three different types of friendships between two polities:
Philiai,
symmachia, and
epimachia. Both
symmachia and
epimachia were types of alliances, with the former committing States to support each other in battle and the latter requiring parties to assist each other if one suffered an invasion.
Philiai, then, made the important distinction of denoting friendship between polities but did not give the treaty partners the status of allies.
Romans had a similar word
amicitia, which was a state of diplomatic relations which could coexist with an alliance, or exist without it. The Romans employed a practice of establishing peace and friendship with polities on its peripheries, though in practice these relationships were usually built on unequal treaties, requiring the neighbour to support Rome militarily, though not necessarily the reverse.
Terminology In the
Soviet Union,
Agreement of Friendship, Cooperation, and Mutual Assistance or
Treaty of Friendship, Cooperation and Mutual Assistance (
Russian: Договор о дружбе, сотрудничестве и взаимопомощи) was a standard Russian language reference to various treaties both internally, between the Soviet Republics, and externally, with countries considered friendly. This terminology is still in use for some
post-Soviet states. The terminology was used in many so-called "friendship treaties" the Soviet Union made, but also was used in the
Warsaw Pact. In the
United States, these types of treaties are commonly a
Treaty of Friendship, Commerce and Navigation. More than a hundred "Treaties of Friendship, Commerce, and Navigation" have been signed since independence. Since 1946, these treaties have dealt with commercial matters concerned with the protection of persons, natural and juridical, and of the property and interests of such persons. They define the treatment each country owes the nationals of the other; their rights to engage in business and other activities within the boundaries of the former; and the respect due them, their property and their enterprises. == List of friendship treaties ==
