If we take this brief glimpse of the civilization of the Jaredite nation quoted above, and couple it with the promise of God to Moriancumr, we have every reason to believe that the Jaredites became a very great, prosperous, and powerful people. Their occupancy of the western world, however, was confined to the northern continent. Here their civilization rose, and here it fell, after enduring between fifteen and sixteen hundred years, if we accept the Hebrew chronology for the date of the confounding of language at Babel. _Numbers_. The number of Jaredites, of course, varied at different periods of their long national existence. In the reign of the fourth king, Omer, a grievous civil war broke out among them which "lasted for the space of many years," and led to "the destruction of nearly all the people of the kingdom." [25] From time to time they were subject to these civil wars which very naturally checked the increase in their population. Still they became very numerous, sufficiently so, as already shown, to occupy an immense empire of country, extending from the Isthmus of Panama northward, including Central America, Mexico, thence northward to the great lakes, and from the eastern slopes of the Rocky mountains to the Atlantic Ocean. In their last great civil war, after it had raged many years, we are informed by the sacred historian that there had been slain by the sword "two millions of mighty men, and also their wives and their children." [26] Upon which the late Orson Pratt remarks, in a foot note on the passage, that including the wives and children of the two millions of men who were slain, "the numbers would probably have been from ten to fifteen millions." Their numbers may have been even greater than this at other periods of their history. _Literature_.
