Alvarado was born in Ciudad de la Esperanza, Intibucá, but later lived in Gracias a Dios in the department of Lempira, where he worked as a surveyor.
He was a member of the Constituent Assembly and was elected President of this Parliament.
On 26 October 1838 under the provincial government of José María Martinez Salinas, the province of Honduras had declared itself a separate state.
On 25 September 1839, at San Pedro Perulapán, the troops of Honduras surprised Francisco Ferrera, who was wounded and fled to Nicaragua.
Although Alvarado stated that he withdrew for reasons of health, the political and military pressure from Morazán contributed to it.
