[1][2] Clube União Micaelense was founded in late 1911 but it has links to the Sociedade Promotora da Agricultura Micaelense (English: Promotional Society of Micalense Agriculture) and Sociedade dos Amigos das Letras e Artes (English: Society of Friends of Arts and Letters) which was founded on 9 September 1848 by António Feliciano de Castilho.

The new Clube União Micaelense specialised in a number of sports including football and made use of a field at Mercado Agrícola in São Gonçalo.

[4] To get to this stage Micaelense won a qualifying tournament at the expense of Angústias Atlético of Horta, SC Lusitânia and finally CS Marítimo of Madeira.

[3] Micaelense have never been able to match their quarter-final appearance in the 1961-62 Taça de Portugal but in 2002-03 did reach the fifth round of the competition following victories against Casa Pia (4–2), Esposende (3–0), Sp.Pombal (3-3, 5-4 pens) before finally bowing out 4–1 away to Académica.

The descent culminated in a further relegation at the end of the 2011–12 season and they are now back in the Campeonato de Ponta Delgada (District Championship) where they previously played up until 1993–94.
