The origins of the Micro-Estrella division lies in midget wrestling, which in Mexico was popularized in the 1970s when promoters used the American concept and had a number of Mexicans with dwarfism, individuals with an adult height of less than 147 centimetres (4 ft 10 in), perform as a "special attraction" on lucha libre shows.

In the early days, popular wrestlers included Gran Nikolai, Pequeno Goliath and Arturito.

[a] On April 30, 2017, CMLL began promoting a series of matches for the Micro-Estrellas ("Micro Stars") division, with all competitors being people with dwarfism.

In the first match in the new division, Microman and Gallito defeated the team of Mije and Zacarías el Perico.

CMLL held a six-man torneo cibernetico elimination match featuring Microman, Chamuel El Gallito, Zacarías el Perico, Guapito, and Átomo on December 25, 2019 to determine the first CMLL World Micro-Estrellas Champion.
