Baden-Powell's original intention was that Scouting should be for boys between the ages of 11 and 18. But younger boys, seeing the fun and adventure older brothers and friends were having as Scouts, began asking to join too. However, their physical development and interests considerably different to other boys over the age of 11, and Baden-Powell appreciated that training must therefore be designed on quite separate and distinctive lines although being complementary to each other.

In 1914 'Junior Scouts' were introduced and in 1916, they became 'Wolf Cubs'. In 1966, as part of a 'modernisation' plan, a number of sweeping changes were introduced in preparation for the years ahead and the Section became known as Cub Scouts. New proficiency and Training schemes were introduced and the Cub Scout Law and Promise were revised.

In 1991, the Cub Scout Training Programme was updated again, based on the themes of Challenge & Adventure.

Even after 80 years, the Cubs section of the Scout Association is as strong as ever. There are nearly a quarter of a million Cub Scouts, consisting of both boys and girls, in the United Kingdom. There could be many thousands more, but because of the lack Adult Leaders in some areas, they have not got the opportunity.
