Antonio Tejero Molina was a Spanish lieutenant colonel of the Guardia Civil. He was the most prominent figure in the failed coup d'état against the newly democratic Spanish government on 23 February 1981 when he stormed the Congress of Deputies with 200 armed Civil Guards. For this reason, he was sentenced to thirty years imprisonment for the crime of consummated military rebellion, with the aggravating circumstance of recidivism; he had previously been arrested for his involvement in the failed coup attempt during Operation Galaxia in 1978.
