Eleven athletes, dissatisfied with Independente Esporte Clube, left their club and founded an amateur club called Onze Tufões (meaning Eleven Hurricanes).[2]
On May 30, 1975, with the help of Casimiro de Abreu's city hall, Casimiro de Abreu Esporte Clube was founded by the eleven athletes.[2]
In 2000, Casimiro de Abreu professionalized its football section.[2]
The home stadium Ubirajara de Almeida Reis,[1] named after one of the club founders, has a capacity of 3,000 people.[4] The stadium is nicknamed Caecão, which is the augmentative form of the club's acronym CAEC.[5]
