Subcomandante Elisa (born María Gloria Benavides Guevara; January 1955) is a Mexican activist from Monterrey, Nuevo León. In the 1980s and early 90s, she served as a subcomandante in the Zapatista Army of National Liberation (EZLN). She was arrested in February 1995 in connection with the 1994 Zapatista uprising. In 1996, the Mexican government acknowledged it was a wrongful arrest and acquitted her of all charges. Today, she is a professor at the Autonomous University of Social Movements (part of the Mexican Solidarity Network).

Benavides studied at the Faculty of Medicine from 1971 to 1972, where she was exposed to leftist ideas converging from multiple radical currents, particularly Juventud Comunista de México (Communist Youth of Mexico), Liga Leninista Espartaco (Spartacus Leninist League), and Obra Cultural Universitaria (University Cultural Work). According to Héctor Escamilla Lira, a prominent guerilla in the Liga Comunista 23 de Septiembre (September 23 Communist League), one of the reasons left-wing movements thrived during this time was the lack of repression in the late 1960s and early 70s. He notes that “the anti-communist fury broke out later, with the arrival of [Nuevo León governor] Alfonso Martínez Domínguez."

This period of political freedom allowed the teenage Benavides to come of age as a budding radical leader. From this point on, she was deeply involved in Mexico's revolutionary movements, one of which would eventually win out: the Zapatista.

The 1970s saw Benavides join the FLN (National Liberation Forces), the foremost radical group in Mexico since its founding in 1969. The FLN is widely considered to be a precursor to the Zapatista Army of National Liberation (EZLN). Both groups had a radical leftist ideology and a desire to actively combat the exploitation of indigenous Mexicans.

Benavides was first arrested in 1974 during a house raid, during which she also lost her husband. After her release, she rejoined the movement, only to lose her second husband and infant daughter in another military raid.

In the early 1980s, Benavides took on a more significant leadership role in the movement. She was among the non-indigenous members of the FLN who founded the EZLN on November 17, 1983. FLN leader César Germán Yáñez Muñoz gathered six revolutionaries (three indigenous, three non-indigenous) at a camp called La Garrapata to establish a more action-based initiative.

In an interview with Radio UNAM (National Autonomous University of Mexico) in 1994, Benavides commented on her reasons for joining and remaining with the Zapatista army: "I entered there because I saw the situation that people lived. So I thought about how to solve this problem, because I didn't know if there were companions in the mountains. But when they told me that there is a group of comrades who are fighting for the people, then one day the insurgent comrades came down in the village, that's when they explained to me what they wanted, why they fought."

Much of Benavides' activism after 1983 involved working as a translator for indigenous groups in the small villages of Chiapas, particularly in the Lacandon Jungle. At this point in time, the EZLN was devoting considerable resources to its social work in Chiapas, including health and education programs otherwise unavailable to the marginalized indigenous population. All decisions were made in tandem with indigenous councils in the individual regions. This practice was in keeping with the EZLN's larger goal: to produce, through a sort of peaceful vigilantism, the conditions that were necessary for the continuous reproduction of identity and sovereignty in civil society The movement itself was heavily influenced by the Italian Marxist philosopher Antonio Gramsci, who emphasized the necessity of forming a "collective will," or "the attainment of a cultural-social unity through which a multiplicity of dispersed wills, with heterogeneous aims, are welded together with a single aim, on the basis of an equal and common conception of the world, both general and particular." This is the first step in constructing an alternative historical bloc to the one put forth by the ruling class, which he believes is the key to inverting hegemony and beginning to dismantle an oppressive state.
