Why is "July 1822 Spanish coup attempt" trending?

Wikipedia Overview

The July 1822 Spanish coup attempt, also known as the coup d'état of July 7, was a failed coup d'état that took place in Spain during the Liberal Triennium. It was intended to put an end by force to the constitutional regime, reestablished after the triumph of the Revolution of 1820, and to restore the absolute monarchy. As Juan Francisco Fuentes has pointed out, "it was the most serious attempt of absolutist coup d'état, which not in vain had its epicenter in the Royal Palace of Madrid", although it had numerous ramifications outside the capital, which demonstrates "the existence of a relatively broad and mature plan". "It marked a turning point in the course of the Triennium", stressed Ángel Bahamonde and Jesús Antonio Martínez. The same thesis is held by Pedro Rújula and Manuel Chust: "The July crisis marked in a traumatic way the evolution of the constitutional regime".
