apertura a la población

[solfinker]

posibilitando la apertura de ésta a la población dejando de ser un lujo solo al alcance de nobles y monarcas

My attempt:

making thus possible the opening of this one to the population stopping to be a luxury within reach of the nobility and monarchs only

[gernt]

…bringing it within reach of the general population and never more a luxury available only to kings and the nobility.
