Many Scout Groups claim the title of oldest Scout Group in their respective countries. Due to the rapid growth of Scouting, it took some time for central organisations to be established, and the earliest groups were only registered some time after their first meeting. Some groups first met under the banner of other organisations, including the Boys' Brigade, Church Lads' Brigade, YMCA, churches or schools, and only later registered with central Scout organisations. Some maintained dual registrations. This makes it impossible to establish which groups started first. Today, national Scout associations often do not take a stance as to which was the first group in their country.
