Interpersonal relationships A variety of rivalries occur in interpersonal relationships.
Sibling rivalry is a type of
competition or animosity among siblings, whether blood related or not. Siblings generally spend more time together during childhood than they do with parents. The sibling bond is often complicated and is influenced by factors such as
parental treatment,
birth order, personality, and people and experiences outside the family. Sibling rivalry is particularly intense when children are very close in age and/or of the same gender and/or where one or both children are
intellectually gifted. According to a review by Macionis, older siblings tend to report rivalry peaking in childhood, while younger siblings report a peak later during early adolescence. Rivalries also occur between people who have competing romantic interests in the same potential romantic partner: People employ a number of mechanisms to counter romantic rivals, such as discrediting the characteristics of the rival that the romantic partner might seek in a long-term relationship. and

Economics and politics In
economics, both goods and producers of goods are said to be rivals. A
good is said to be
rivalrous if its
consumption by one
consumer prevents simultaneous consumption by other consumers. Companies that compete to sell the same goods can become rivals as each seeks to convince consumers to purchase its products, to the exclusion of the products of its rival: is one of the oldest and bitterest in the history of English

Rivalries between nations can induce them to compete "over naval armaments, foreign aid, cultural influence, and athletic events", the rivalry in each case occurring within the context of the competitors having "labeled one or more of their adversaries as worthy of particular concern and attention". It has been noted that "while all great powers, almost by definition, are competitors, only some brand each other as rivals", with rivals being "competitors who have been singled out for special attention in some way": == International rivalry ==
