Why is "1936 Carlist coup attempt" trending?

Wikipedia Overview

1936 Carlist coup d'état was a plan to topple the Spanish republican government and install a Traditionalist monarchy. It was conceived by top executive of the Carlist organisation, Comunión Tradicionalista, and developed in March and April 1936. Preparations were under way until July 1936, though since June 1936 the plan was gradually being abandoned. The scheme, named Plan de los Tres Frentes, envisioned some 25,000 armed requeté volunteers advancing from Navarre, Maestrazgo and Extremadura towards Madrid, combined with an attempt to seize key governmental buildings by Madrid-based conspirators. The political leader behind the plan was Manuel Fal Conde, the key military planner was general Mario Muslera Planes, and the coup was tentatively to be led by general José Sanjurjo Sacanell. The scheme of a Carlist-only insurgence did not enjoy unanimous support within the CT; it was undermined by a competitive plan of a joint Carlist-military coup, promoted mostly by the local Navarrese executive. Eventually this alternative option prevailed; Plan de los Tres Frentes remained in the preparation phase and there were no attempts to put it into action.
