Overview
A sister city or a twin town relationship is a form of legal or social agreement between two geographically and politically distinct localities for the purpose of promoting cultural and commercial ties.
While there are early examples of international links between municipalities akin to what are known as sister cities or twin towns today dating back to the 9th century, the modern concept was first established and adopted worldwide during World War II.
Origins of the modern concept
The modern concept of town twinning has its roots in the Second World War. More specifically, it was inspired by the bombing of Coventry on 14 November 1940, known as the Coventry Blitz. First conceived by the then Mayor of Coventry, Alfred Robert Grindlay, culminating in his renowned telegram to the people of Stalingrad (now Volgograd) in 1942, the idea emerged as a way of establishing solidarity links between cities in allied countries that went through similar devastating events. The comradeship between the two cities continued, when again in response to the Battle of Stalingrad, 830 women in Coventry – led by the subsequent Mayor Emily Smith – had their names embroidered on a tablecloth along with the words "Little help is better than big sympathy" and sent it, along with money (each donated six pence), to the people of Stalingrad. The tablecloth can now be seen at the Panorama Museum of the Battle of Stalingrad. The twinning between Coventry and Stalingrad was formalized in 1944 and, after the end of the war, similar links were established to foster friendship and understanding among former foes as an act of peace and reconciliation, with new twinnings between Coventry and German cities: Kiel as early as in 1947 and Dresden in 1956. In 1957, Coventry was officially twinned with Belgrade, even though the link actually dates back to 1953 when then Yugoslav Ambassador visited Coventry and offered a gift of timber from his native country for use in the new Civic Theatre, which when finished was named The Belgrade Theatre.
The purpose of twinnings was then expanded to encourage trade and tourism or to reflect other links, such as towns sharing the same name or migration links. By the 2000s, town twinning became increasingly used to form strategic international business links among member cities, and may include localities of any scope such as villages, prefectures, or countries.
