The green ribbon is a ribbon in the color of green.
Mental Health Awareness is represented by a green ribbon. In the 1800s, green was the colour used to label people who were considered “insane”.
In 17th-century England during and after the English Civil War the wearing of a sea-green ribbon symbolized affiliation with the ideals of the Levellers and later in the century with radical Whiggism.
The green ribbon and sprigs of rosemary were symbols of support for the Levellers during the English Civil War and English Interregnum. At the funeral of Thomas Rainsborough (a Member of Parliament and also a Leveller leader who had spoken at the Putney Debates) there were thousands of mourners wearing the Levellers' ribbons of sea-green and bunches of rosemary for remembrance in their hats, as there were the next year, 1649, at the funeral of Robert Lockyer a New Model Army Agitator hanged by Oliver Cromwell for mutiny.
The Green Ribbon Club was one of the earliest of the loosely combined associations which met from time to time in London taverns or coffee-houses for political purposes in the 17th century. It had its meeting place at the King's Head tavern at Chancery Lane End, so was known as the King's Head Club. It seems to have been founded about the year 1675 as a resort for members of the political party hostile to the court. As these associates were in the habit of wearing in their hats a bow, or bob, of green ribbon, as a distinguishing badge useful for the purpose of mutual recognition in street brawls, the name of the club was changed, about 1679, to the Green Ribbon Club. The 'Green Ribbon' was the badge of The Levellers in the English Civil Wars in which many of the members had fought and was an overt reminder of their radical origins.
In 1998, Margaret Bruce, a Pastoral Associate at St. John the Evangelist Catholic Church in North Dakota, sought a way to support farm families and came up with the idea of a green ribbon and a card that read "We care through prayer." Around the same time, the National Catholic Rural Life Conference (NCRLC) began receiving emergency calls from farm families in stress and saw that the situation was getting worse across the country. In November 1998, NCRLC launched the Green Ribbon Campaign at their 75th anniversary meeting. They developed and began to disseminate rural crisis packets to help parishes deal with the growing rural crisis.
