A partnership is an arrangement where parties, known as partners, agree to cooperate to advance their mutual interests. The partners in a partnership may be individuals, businesses, interest-based organizations, schools, governments or combinations. Organizations may partner to increase the likelihood of each achieving their mission and to amplify their reach. A partnership may result in issuing and holding equity or may be only governed by a contract.
Partnerships have a long history; they were already in use in Medieval times in Europe and in the Middle East. In Europe, the partnerships contributed to the Commercial Revolution which started in the 13th century. In the 15th century the cities of the Hanseatic League, would mutually strengthen each other; a ship from Hamburg to Danzig would not only carry its own cargo but was also commissioned to transport freight for other members of the league. This practice not only saved time and money, but also constituted a first step toward partnership. This capacity to join forces in reciprocal services became a distinctive feature, and a long lasting success factor, of the Hanseatic team spirit.[1]
