Historically, the essential factor for the establishment of a global language is that it is spoken by those who wield power. Latin was the lingua franca of its time, although it was only ever a minority language within the Roman Empire as a whole. Crucially, though, it was the language of the powerful leaders and administrators and of the Roman military - and, later, of the ecclesiastical power of the Roman Catholic Church - and this is what drove its rise to (arguably) global language status. Thus, language can be said to have no independent existence of its own, and a particular language only dominates when its speakers dominate (and, by extension, fails when the people who speak it fail).
