Emelec

The club was found after an assembly of employees at the Empresa Eléctrica del Ecuador, an electric company in Guayaquil, decided to start an amateur sports league. The initiative was spearheaded by George Capwell, the executive officer of the company who came from the United States. The first sports played in the club were baseball, basketball, boxing, swimming, handball, and football. Capwell did not enjoy football, so the sport was supported only by his employees in non-official but recognized championships. This changed in the 1940s, when Capwell finally lent his support, resulting in the club winning several official local championships, building their own stadium, and hosting the 1947 South American Championship entirely in it.

In 1957, the club became the first national champions in football with a "dream team" that included Derek Haack, Cipriano Yu Lee, José Vicente Balseca, Cruz Ávila, Mariano Larraz, Carlos Alberto Raffo, Jaime Ubilla, Daniel Pinto, Rómulo Gómez and Suárez-Rizzo; they were coached by Eduardo "Tano" Spandre. Since then, they have accumulated thirteen more national titles, placing them 2nd in the national title count behind Barcelona with 15 titles and followed by El Nacional with 13. They have also won seven local titles (two in the amateur area and five in the professional era).

In the 1990s, the football team saw success internationally. In 1995, they reached the semi-finals of the Copa Libertadores; they lost to eventual champions Grêmio. In 2001, the team was close to becoming the first Ecuadorian club to win an international title when they were a finalist in the 2001 Copa Merconorte. In the finals, they lost to Millionarios 3–1 on penalty kicks after tying on aggregate 2–2.
